Optimize the design of lightning protection. Products by optimizing the three, four lightning to power Lightning 4000V, the video signals for communications, Lightning 2000V, adapt to the outdoor complex environment. Large angle laser illumination. Products nighttime laser illumination angle of 50 degrees, significantly better than similar products in the industry, greatly improving the laser night vision night vision field of view. The long-life design products independently developed laser die, life expectancy of 20,000 hours. Fatigue testing machine by 10000 times. After sales service. My company will be sold to provide quality service to ensure that normal users can efficiently use my company's products. The life time of green laser pointer can be more than 3000 hours.
I will provide a supply list, and warranty coverage to the list shall prevail, if the list is missing, the responsibility borne by us. I supply the equipment from the opening date of acceptance, free warranty period for product one year after delivery, for life to provide maintenance services. Equipment needs to be repaired after the warranty expires, you only pay the cost of maintenance fees (a list of maintenance costs, including travel expenses). After a system failure, I provide 7 × 24 hours of after-sales maintenance services, teleconferencing service response time less than 1 hour response time to arrive at the scene no longer than four hours to completely solve the problem within 48 hours. The customer maintains laser pointer well.
Low-light CCD camera technology and night vision technology has made great progress, but remains high noise in low-light environments, image monitoring device received the fuzzy, low resolution image. The reason is that the light is too weak. Infrared semiconductor laser light source can radically improve the night, especially the night the effect of long-range shooting. Infrared semiconductor laser light source is designed for the configuration of infrared night vision systems, remote infrared light source; as well as infrared cameras, black and white CCD camera or night vision system for night and 24 hours, weather conditions, surveillance cameras, lighting, distance from a few meters to several kilometers. Therefore, the manufacturer wants to enhance the life time of green laser .
Laser beam compression lens is mainly used for the laser beam divergence angle compression, the observed average distance in order to properly observe the target at different distances, usually with zoom lens, close to the beam divergence angle, so that lighting a large range of light intensity becomes weak, the imaging part because light intensity saturation, distance to the beam divergence angle, such a small range of lighting, the light intensity is strong, imaging, some will not be long-distance attenuation, thereby increasing The large viewing distance. The main purpose of the spot integer to the semiconductor laser spot into the whole round or square. Therefore, more and more customers will be attracted by green laser led .
We know that the semiconductor laser output beam is elliptical, horizontal and vertical divergence angle is generally θ ‖ × θ ⊥ = 8 o x 40 o. Can not be used for direct lighting observation, so the whole into a round or square. For display monitor observation usually finishing a rectangular. CCD photosensitive surface is rectangular, and its length and width ratio of 3:4, so if the laser spot shaping for this proportion of the moment line, then just match each other, the resulting visual effect is very good. If the angle of field of view in one direction, just as the divergence angle of the laser level (such as 8 o). In practical applications, taking into account the versatility of the lens, beam divergence, for example, compressed to 0.5 o is possible, by the above calculation f = 24mm, D = 2 × 24tan20 o = 18mm. Here will introduce one of types of batteries of green laser pointer .
