The customer is deeply impressed by the investment in development of laser pointer .
When a ray particles into the tube, it makes the gas ionization tube, the resulting electron is accelerated in an electric field, increasing energy, the electronic control of the gas molecules with the collision, and ionization of the gas molecules, resulting in electronic ... ... In this way, a ray particles into the tube after a large number of electrons can be generated. These electrons reach the anode, cations to the cathode, the outer circuit to generate a pulse discharge, the use of electronic equipment and discharge times can be recorded. Advantages: great magnification, very sensitive, use it to detect radioactivity is very convenient. Disadvantages: it is for a different phenomenon-ray pulses produced by the same, it can only be used to count, but can not distinguish between types of radiation. The leaders of the laser pointer company will attach more importance to the research of laser pointer .
If both a large number of particles, or particle radiation to two very short interval of time (less than 200μs), they can not count. High-speed particles from the emulsion layer of film through, which makes the formation of silver bromide grain ionization potential like. The obvious and fixing can show particle tracks. The advantage of latex is a continuous photographic record, track and receive a complete, easy to determine the nature and behavior of particles. Definition: the bombardment of nuclei in the other particles generated in the nucleus of a new process called nuclear reactions. Laws: conservation of mass, charge number conservation. Several artificial nuclear transformation reaction equation. Rutherford discovered the proton equation: Chadwick discovered the neutron equation: ? Joliot Curie discovered artificial radioactive isotopes and positron equations. The expert group of laser pointer is researching the new technology of laser pointer .
Only naturally occurring radioactive elements over forty, but with artificial radioactive isotopes obtained by a thousand, which makes a wide range of applications of radioisotopes. As the number of isotopes of the same nuclear charge, so the chemistry of the same nature. The use of radioisotope release of radiation (α rays, β rays, rays) exposure to different characteristics of objects, a variety of purposes. The use of metal components-ray release of the existence of blisters, cracks, etc., that the use of-ray detection. Skills through the use of radiation and material relationship between the thickness and density, can use to check the thickness of various products in sealed containers and the height of the liquid in order to achieve automatic control. The quality enhancement of laser pointer is the main topic of today’s meeting.
The use of ionizing radiation to the air while the air becomes conductive gas to remove fiber, textiles static. With irradiation plant, causing a good variation of plants, it can also be used sterilization, medical treatment and so on. Radioisotope with the same elements as the non-radioactive isotopes have the same chemical properties, if the number of radioactive isotopes of an element braced, then the elements no matter where, it is also through the same process of radioisotopes. Continue to emit radiation and radioactive elements, and then detecting these rays, you can know the whereabouts of the elements, this purpose is called radioisotope tracer atoms. The laser pointer company focuses on the technology improvement of laser pointer recently.laser pointer has the brilliant remote control function

laser pointer has some strict requirement towards the production
laser pointer has some strict requirement towards the production.
Come to rely on the number of dissolved depth of the laser energy density corresponding to the organic polymer has been dissolved by the laser are given. Come into contact with solid dissolved with femtosecond laser is very short will be able to complete the dissolution process, so this process as a solid direct gasification (or solid direct liquefaction). This time, the lattice is heated in 1ps, the result is an object into a gaseous or plasma state, followed by rapid diffusion in a vacuum. The thermal conductivity of the entire process in the first approximation, be ignored. Practice is confirmed by the femtosecond laser processing and is able to provide a precise and clean process to the metal (and other solid) processing. The blue laser beam light is emitted from the blue laser pointer .
(2) lattice temperature, is written in integral form. The equation describes the heat of the molten metal by the laser in the next. When the condition is satisfied, the electron temperature is stable, then (11) can be simplify. Ignored, we get formulas show that. In the the femtosecond environment, the lattice temperature remains far less than the electron temperature. This allows us to ignore the lattice temperature in the formula (10). When the conditions are met, (10) and (12), the analysis becomes very simple. In this case, due to energy transfer to the lattice, leading to electron cooling. The electron temperature and lattice temperature after laser irradiation by the formula. We note that the lattice in the laser irradiation can reach temperature but also determined by the electron cooling time. laser pointer is not very stable compared with the red laser pointer.
After the laser irradiation, the lattice temperature and theoretically attainable lattice temperature is basically the same. Under the conditions of the femtosecond and picosecond (7) and (13), the lattice temperature equation is the same. Therefore, given the conditions of strong evaporation (8) (9), the pulse energy density threshold and dissolved depth did not change. In this case, in the picosecond range, the dissolution depth and laser energy on the number is still valid. In our derivation, have ignored the solute electronic thermal conduction. On the assumption that it is very rough description of the picosecond range laser dissolved metal. Under these conditions the laser dissolution is accompanied by electronic thermal conduction within the metal melt region formation. The wavelength of the green laser beam light of laser pointer is 532nm.laser pointer is efficient is burning the match
Nevertheless, the surface area, we will continue to evaporate as direct gasification by the solid (or solid direct liquefaction), changes in the internal liquefaction only reduce the accuracy of the dissolution process (see next). Nanosecond laser dissolved in this brief discussion, the following kinds of conditions to meet. So, electronic and lattice temperature there, (1-3) simplifies to a variety of experimental and theoretical studies have indicated that the laser would be heated metal target. Within the scope of this laser, the laser energy is absorbed before heating the metal surface to the melting point, and then to the evaporation temperature. Than the melt, the metal evaporation requires more energy. In the whole process, import the solutes in the heat transfer occurs when energy is missing. The green laser beam light of laser pointer is much easier to be affected and influenced by the ambient condition.

This is the picture of the battery of Laser Pointers
This is the picture of the battery of Laser Pointers .
Single parts are exposed to wear and tear from the point of view, dealing with different print job is not the same, know that you can easily understand that these are also used after a cycle of toner cartridges, which contains why the different parts of the state, which renovation industry is the use of old pieces of the difficulty encountered when one of the old pieces are vastly different. Rotating components wear: We all know that in the printing process drum, magnetic roller, charging roller are constantly rotating in the process of rotating parts subjected to wear and tear associated with the completion of one cycle of printing tasks, printing and continuous printing page after page of wear experienced by great distinction, with the EX drum, for example, every time you print a drum circle to turn 9, if a page to print. The battery of Laser Pointers should be changed regularly.
6,000 pages in a print cycle, the drum circle of rotation 54000; if each print job is set to 5, the same task to complete 6000 print drum to rotate 25000 circle, the greater the drum that print jobs withstand the wear and tear smaller, the magnetic roller and charge roller, too, so remember that print on continuous wear of the smallest parts. Wear and tear on the parts toner: toner on the relevant parts are worn, imaging and non-image areas are exposed to wear and tear is different, even though every day dealing with the same print job is not much, but we need to know this circumstances the use of components is the most unreasonable.
For example when you want to test has nothing to do with the blackness of the components, with no need to ask its parts have to meet the requirements of the blackness, no need to use qualified to do this with the production of materials testing, and this is one of your cost of test methods, especially in the development of new products, to test the wear resistance of many parts, the use of expired toner and some performance parts also failed to complete the task, and so the choice of too much, do not go into here , we need to work flexibly. The battery of Laser Pointers shouldn’t pollute the environment.
Therefore, maintenance, be sure to check and determine the failure to grasp the correct way. Dismantling can not be blind, so as not to expand the fault. In general, more mid-range models, as long as the main supply power supply is working properly, failure will show fault code, according to the meaning of the code, check the corresponding fault location (such as HP, Canon, Epson and other high-end printer, work has shown the status of the "display"). Mid-range models have adopted the following panel lights to indicate working status and failure meaning, according to the indicator status and meaning of troubleshooting (such as HP 4L, 6L and other models). Laser Pointers sells better at the Christmas.

when the galvanometer scanning to the white position
when the galvanometer scanning to the white position.
with the price of the 450B-type stepping motor on the difference between more than two hundred yuan. This is also the key to determine the X-axis, we are here for the user to expand the cost to see the equipment, fast return investment, this is a brand to stand the severe test of the market laser marking machine price. The wireless technology of green laser pointer is generally classified into infrared and radio frequency (RF). Jingjiang brand on the difference of three or four thousand dollars and the price of other places, or do not wear fine prestige brands every year length l, the same is a laser pointer to create a very thin rails and high hardness materials the product up and running a phenomenon often have jitter tremble.
the most critical parts of the laser pointer is a bed, cheap. Different brands of heavy stone laser pointer prices very different from the domestic lens which is divided into the production of imported materials and domestic production of materials two, you must use a diameter greater than or equal to a 25mm materials, the user is in a very short occurs within the time accuracy is not high, and lost step rust failure, small gantry of some inferior products do less than 200mm width, cutting speed of the machine, sub-import lenses, if compared to the reliability and maintenance services convenient and affordable. Otherwise, signals between the receiver and emitter of the green laser pointer products will be blocked.
The precise technical drawings assembled with cheap, engraving speed would not open. Than 100 one by one test of our QC will be more than line assembly, and the machine can pass around material, first of all, so carving the wood of large size can also ease the price of laser marking machine, weight, and processes are about the same They are often on the production floor the first line, the other is the appearance of the spindle motor. Say that the electrical part of the cost of just this one on the difference between $ 5,000 and made laser tube is also mixed. Infrared green laser pointer products are sold at low prices.Graver thousands of times per second, the frequency of vibration. The size of the driving force of the electromagnetic field or a long wooden box will not fit into. This requires manufacturers to provide strong after-sales service guarantee, such as 300X400 format. Without the network. From first principles point of view, before and after the machine can pass the material and have a cutting platform, to reduce the visual effect of the sawtooth, many new devices are not as good years of "third kind". So most of the domestic laser pointer made laser tube, reflective lenses are consumables. metal obstacles may produce shielding effect to interrupt the signal of high quality green laser pointer products.
Select the machine to select 600x900 format. Now to describe, in which only the child of this ultra-fine engraving technology characteristics. Can do anything, 80w machine can cut 20mm thick acrylic, high-resolution line engraving signal must be responsible for the formation of the internal concave contours of the network points, a certain service life. Experts see Road, some joint-venture factory plant of Health stepper motor. The use of performance and service life is also a great gap, high-quality cold-rolled steel production casing caused by the phenomenon of serrated edge appears.

The sphere of application of green laser pointer
The sphere of application of green laser pointer
Class III: the output laser beam directly into the eye if would have hurt, for some security reasons, further divided into IIIA and IIIB level.
Class IIIA laser for the visible light of continuous output of 1-5mW laser beam, the beam energy density of no more than 25W/m-m, avoid using afar observed IIIA laser devices, this may increase the risk. Typical applications IIIA and Class II level have a lot in common, such as laser pointer, laser scanners.
III B class of 5-500mW of continuous laser beam to observe directly in danger. green laser pointer has been divided into several varieties.But minimum irradiation distance of 13cm, the maximum exposure time of ten seconds the following for safety. IIIB typical applications such as laser spectroscopy and entertainment lighting show.
ClassIV: high-output continuous-wave (greater than 500mW), higher than the third level, there is a fire hazard, diffuse reflection also at risk. Typical applications such as surgery, research, cutting, welding and micro-mechanical processing.
According to different wavelength, green laser pointer has been divided into several varieties.Although the laser safety levels have been defined, but for the human body, especially the human eye, the damage is different at different wavelengths, and therefore, although two or three of the laser, the same should be noted.
Different wavelengths of laser eye injury site
Wavelength Division Wavelength (nm) primary site of injury
180-400 UV laser cornea, lens
Visible laser 400-700 retina, choroid
700-1400 near-infrared laser retina, choroid, lens
, The far-infrared laser corneal 1400-106
Long-term operating environment in Laser eye workers are long-term effects. In operation and use of lasers, even if not directly by the laser irradiation, resulting in injury accidents. Different laser wavelength of green laser pointer has different harm to people.However, the anti-out laser rays through walls or other objects produced by micro-reflections, long-term work in this environment of people, a high incidence of cataracts.
Prolonged exposure to green laser light, especially when the laser pointer over 5 mW of power, just a few seconds may cause functional vision of the human eye damage.
Before the eyes of my colleagues once smashed by the laser. The results gave the company lost a little money. The key is self-inflicted injury, loss is difficult to estimate. Especially for industrial processing lasers are now engaged in those who are even more so. The damage degree of green laser pointer depends on the power of it.The safety level of laser processing are generally four (most dangerous), and now there are many applications of laser is not visible in the scope, the more light that is not visible, the more dangerous. Can see the laser, most people know not to look directly at, but not visible only rule of thumb to determine where there is no light, should not be read.
Class III: the output laser beam directly into the eye if would have hurt, for some security reasons, further divided into IIIA and IIIB level.
Class IIIA laser for the visible light of continuous output of 1-5mW laser beam, the beam energy density of no more than 25W/m-m, avoid using afar observed IIIA laser devices, this may increase the risk. Typical applications IIIA and Class II level have a lot in common, such as laser pointer, laser scanners.
III B class of 5-500mW of continuous laser beam to observe directly in danger. green laser pointer has been divided into several varieties.But minimum irradiation distance of 13cm, the maximum exposure time of ten seconds the following for safety. IIIB typical applications such as laser spectroscopy and entertainment lighting show.
ClassIV: high-output continuous-wave (greater than 500mW), higher than the third level, there is a fire hazard, diffuse reflection also at risk. Typical applications such as surgery, research, cutting, welding and micro-mechanical processing.
According to different wavelength, green laser pointer has been divided into several varieties.Although the laser safety levels have been defined, but for the human body, especially the human eye, the damage is different at different wavelengths, and therefore, although two or three of the laser, the same should be noted.
Different wavelengths of laser eye injury site
Wavelength Division Wavelength (nm) primary site of injury
180-400 UV laser cornea, lens
Visible laser 400-700 retina, choroid
700-1400 near-infrared laser retina, choroid, lens
, The far-infrared laser corneal 1400-106
Long-term operating environment in Laser eye workers are long-term effects. In operation and use of lasers, even if not directly by the laser irradiation, resulting in injury accidents. Different laser wavelength of green laser pointer has different harm to people.However, the anti-out laser rays through walls or other objects produced by micro-reflections, long-term work in this environment of people, a high incidence of cataracts.
Prolonged exposure to green laser light, especially when the laser pointer over 5 mW of power, just a few seconds may cause functional vision of the human eye damage.
Before the eyes of my colleagues once smashed by the laser. The results gave the company lost a little money. The key is self-inflicted injury, loss is difficult to estimate. Especially for industrial processing lasers are now engaged in those who are even more so. The damage degree of green laser pointer depends on the power of it.The safety level of laser processing are generally four (most dangerous), and now there are many applications of laser is not visible in the scope, the more light that is not visible, the more dangerous. Can see the laser, most people know not to look directly at, but not visible only rule of thumb to determine where there is no light, should not be read.

green laser pointer will be introduced in details in the following.
Therefore, it can detect extremely weak light signals, and convert it into a corresponding electrical signal. Common laser ranging sensors, which record and process issued from the light pulse to return to the time to receive the experience, you can Determination of target distance. Laser sensors must be extremely accurate determination of transmission time, because the speed of light is too fast. Based on consideration of the overall layout, the design uses 16 of the laser head and seven receiver to take "one" shaped arrangement of the way, two-row arrangement, each row of eight, two adjacent laser emission tube interval of 18cm. In order to facilitate the receiving road is reflected back into the laser infrared receiver tube, the installation when the launch tube and receiving tube to each other there is an inclination in order to better receive the signal. This means that God means that God trillionth of 36 seconds ultrashort moment within the light II in 1000 trillionth of a second ultra-short moment. If the supply management of green laser pointer is permitted.
Burst out within a trillionth of a second is equivalent to a global grid of ultra-short moment, power generation, the strong power of several ten times. Generating several ten times more powerful power. Extreme physical conditions in nature only in the nuclear explosion center, the stellar interior and the edge of the universe, black holes can exist. Ray machines, light optical Key Laboratory of scientific and technical personnel repeatedly refresh these two indicators, to create again and again "faster and stronger," the miracle in less than 10 square meters on the optical bench. April 13, 2006, 9 SG Ⅱ device added a new laser output energy to break the record, compared with the previous 5.8-fold, 9-way beam-diameter, 8-way beam 190 mm to 310 mm.
Particle transition to the high energy level on the low energy level E1 of this process called stimulated emission. The characteristics of stimulated emission itself is not a spontaneous transition, but by the stimuli of external photons. Thus exactly the same as the frequency of the particles released from the photon with the original photon direction of propagation, phase and polarization, can not distinguish which one is the original photon, which is generated by the excitation photons by stimulated emission of radiation due to optical radiation is proportional to the energy and photon number of cases, therefore, stimulated emission, optical double the radiation energy increases. Wave point of view, set the external photon is a wave by stimulated emission of photons for another wave, due to the phase of two waves, vibration direction, the direction of propagation and the same frequency. The material of green laser pointer is being purchased.

Schematic laser reflection constitutes 100% of the total reflection mirror and the reflection rate of 90% to 95% of the part of the parallel mirrors placed on the ends to form the cavity material. The emitter of green laser pointer applies the ergonomic design.Cavity in the work material under the action of the pump source, in the distribution of population inversion, spontaneous emission of photons due to stimulated emission of radiation continued to enlarge, producing photons in the resonator mirror after multiple reflections in the non-resonant cavity along the axial direction of the cavity photon escape quickly, and back and forth along the axial direction of the photon transmission, constantly being enlarged, and the direction, gain continuous improvement, and finally from the laser mirror.

The global optimization of green laser pointer system
The global optimization of green laser pointer system
Scientists have yet to figure out the dye molecules and atomic level structure, only know that they work with the material gas of the gas atom, ion structure is not the same; gas produced by the wavelength of the laser has a clear, while the dye laser produces a wavelength range than wide, or a variety of colors. The green laser pointer looks decent in exterior condition.Dye laser in the optical resonator with a grating as the optical components. It can be selected by the color of the laser, as selected from the radio to listen to different frequencies of radio stations broadcasting the same.
Future
Dye laser excitation source is optically pumped, pulsed xenon lamps can also be issued with a nitrogen laser molecular lasers. With a color laser for optical pumping, the results of the laser can produce other colors can be said that the dye laser characteristics.
This can be changed at any time as required lasing wavelength of laser spectroscopy is mainly used for research; many substances have selective absorption of light of certain wavelengths, the resonance phenomenon. The green laser pointer is the first choice if you want to present a gift someone.Analysis of these phenomena with material scientists to understand the material structure; also use these lasers to produce a new laser to study some of the strange phenomenon of the optical and spectroscopy.
Advantages and disadvantages of laser tag and usage
When it comes to laser tag must think of the "need to be careful with" the word, because it is difficult to produce and transport. Of course it is a great product, great market demand for it. However, if it can be used instead of other labels, laser labels that still give it.
One problem is overheating. green laser pointer is controlled by laser switch.Laser printers on the fusion of the Head temperature of 250-300 degrees Fahrenheit to produce a good label, it is imperative to the film base, adhesive and liner combinations are good. Even with a variety of materials are good, such as label printing moves too slow, it will be subject to thermal damage.
Another problem is the label CORNER - This means that labels void. Printing products to repair after damage.
Transported to the user in the hands of the label before, paper suppliers and manufacturers will solve the above problem.
Rotary Laser tag is generally processed on flexible printing equipment. According to Iowa State's vice president of Heinl called RLP, "Laser tag is difficult to produce in the press."
Paper label suppliers need to understand the water needed for laser control requirements can solve such problems curling and presses stuck.You can punctuate emphasis of the briefing on screen by green laser pointer. Whether curling occurred in 81 / 2 "or 11" die-cutting, manufacturers will be difficult to solve this problem.
Adhesives is another factor. Heinl said, "If it's too thin soft, it will roll in on the plot, so it is very expensive repair, unless when in the cutting edge blade with the right, otherwise the dust will press on the plot stuck in the drum."green laser pointer is an instrument that can attract the attention from audience.

The need analysis of laser pointer has submitted to the manager
The after service of laser pointer has been described in the contract.
The need of customer of laser pointer has been analyzed. Including telecommunications, data communications and optical storage laser diode of all, including the pump laser and for the transceiver and the laser light amplification. Telecommunications market have been hit worse than expected, but the network traffic in late 2009 to increase the potential demand-led growth in sales. Is expected to rebound in 2010 will be particularly strong. On the other hand, as more applications directly connected to the network resources rather than DVD-ROM, optical storage market is facing a slow decline. Blu-ray DVD sales are still rising in other areas can offset the decline in sales. As calculated in U.S. dollars, so the appreciation of the yen in 2009 also increased the total sales figure. In 2009 there are many systems on the 40G and 100G discussion. Router - Router connection and the traditional long-distance transmission has finally opened for the 40G market. Although some of the major financial institutions like 100G technology and social networking site, but much work remains to be done to reduce the cost of these systems. Commercial printing equipment industry is in long-term downward trend in the same time facing the digital revolution and the current economic recession. The exception of China printing industry sales growth is very slow. One kind of ultrafast lasers can bring to the image recording area of potential technology is JP Imaging's "miracle plate" (Miracle-Plate) technology. The technique uses ultrafast lasers to replace the traditional printing process aluminum; the laser can be amplified up to 5 times the re-imaging of flat surfaces, thereby greatly reducing the printing industry's consumption of primary aluminum. "This is still a technology rather than a product, but we believe that ultrafast lasers can eventually eliminate the demand for coated offset printing plate," JPI's business manager John Adamson said, "This will reduce costs and bring the whole industry eco-efficiency. " The laser pointer company can meet the need of market.

It shows clearly the market share of green laser pointer
It shows clearly the market share of green laser pointer .
Laser weapons more than 30 years of development history, the key technology has also made breakthroughs in the United States, Russia, France, Israel and other countries have successfully undertaken a variety of laser shooting test. Low-energy laser weapon has been put into use, mainly for the interference and blinding close photoelectric sensors, and attack the human eye and enhanced observation equipment; high-energy laser weapons, chemical lasers, in accordance with the current level over the next five - 10 years is expected to be deployed on the ground and air platforms to use for tactical air defense, theater missile defense and anti-satellite warfare. The laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use. Second, the laser is coherent light. So that the factory can design and manufacture green laser pointer .
The coherent light is characterized by its light waves are in sync, the entire beam is like a "wave train". Again, the laser is highly concentrated, that it would go a long distance will be dispersed or convergence. Laser (LASER) is the 1960s invention of a light source. LASER is the acronym for the English "stimulated emission optical amplification". Laser there are many kinds of size as large as several football fields, as small as a rice or salt. Gas lasers, helium - neon lasers and argon lasers; solid-state lasers have a ruby laser; semiconductor lasers with laser diodes, like the CD player, DVD player and CD-ROM. Each laser has its own unique laser method. To improve the quality and performance of green laser pointer .
A technology of laser processing technology is the use of the characteristics of the laser beam interaction with matter for cutting materials (including metal and nonmetal), welding, surface treatment, drilling, micromachining, and as the light source, object recognition, etc., the traditional application The largest areas of laser processing technology. Laser technology is related to the subject of the optical, mechanical, electrical, materials and testing an integrated technology, the traditional point of view, it can generally be divided into: laser processing system. Including lasers, optical systems, machine tools, control system and detection system. Laser Processing. Including cutting, welding, surface treatment, drilling, playing standard, line, and fine-tuning a variety of processes. green laser pointer has the special appearance such as the gun shape, bottle shape and so on. A high concentration of radiation energy and pigment selective, very short pulse width, laser energy to focus on the role of the pigment granules directly vaporized, crushed, removed from the body through the lymphatic tissue, without affecting the surrounding normal tissue, and its efficacy exact, safe and reliable, no scar, little pain and enjoys popular support. Laser surgery has pioneered a new era of cosmetic medicine. The high-energy ultra-pulsed CO2 laser resurfacing resurfacing to develop the new technology of cosmetic surgery. It uses high-energy, very short pulse laser, so that aging and damage of the skin is instantly vaporized without harming the surrounding tissue, and almost no bleeding during the treatment, can be precise control of depth.
Laser weapons more than 30 years of development history, the key technology has also made breakthroughs in the United States, Russia, France, Israel and other countries have successfully undertaken a variety of laser shooting test. Low-energy laser weapon has been put into use, mainly for the interference and blinding close photoelectric sensors, and attack the human eye and enhanced observation equipment; high-energy laser weapons, chemical lasers, in accordance with the current level over the next five - 10 years is expected to be deployed on the ground and air platforms to use for tactical air defense, theater missile defense and anti-satellite warfare. The laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use. Second, the laser is coherent light. So that the factory can design and manufacture green laser pointer .
The coherent light is characterized by its light waves are in sync, the entire beam is like a "wave train". Again, the laser is highly concentrated, that it would go a long distance will be dispersed or convergence. Laser (LASER) is the 1960s invention of a light source.

The first generation of portable green laser pointer were used for single purpose
portable green laser pointer couldn’t be used to stretch into pointers at the very beginning.
Check the water circulation system flow is smooth (water pipe bend or burst water main); 2, check whether the normal focal length (recalibration); 3, check whether the optical path (re-calibration); 4 Check the plate capped with paper is too thick, the water is too much to (re-corrected); 5, check the beams are parallel to (adjust both sides of the belt); 6 Check that the lens is broken (replacement); 7, check the lenses or laser tube transmitter is contaminated (re-cleaning); 8, check the water temperature is above 30 ° C (to replace the recycled water); On the basis of an extension of other electronic functions, the second-generation portable green laser pointer are developed.The third generation green laser pointer are made up of a locator and laser. The sticky surface wrinkling bubble too much. Move back and forth so that the compression part of the paper has been too much resistance and deformation And backward rotation of the main roller, resulting in shape distortion and sealing. Software settings inappropriate. 3 car belt is too tight; or main roller screw loose; loose or the motor shaft gear, make the car or the main roller Can accurately follow the motor movement caused by the shape distortion and do not seal. 4 shape without distortion but do not seal, software closure compensation value is too small .
The first generation of portable green laser pointer were used for single purpose.
