 Wireless presenter green laser pointer  used by many customers.
The SJ3 laser swinger pentagonal prism with a wedge, the laser is divided into horizontal and vertical two laser beams, so that instruments can not only scan the level of the laser surface, and a laser beam - beam up to meet the needs of the construction. Two types of swinger can handwheel continuously variable transmission, users can be adjusted in accordance with the actual situation of the construction of the laser head speed and, SJ3 type of swinger detector radius of 100 meters. Instrument equipped with various accessories, the SJ2 type is available in a paper target and special accessories, use swinger stops rotating, insert an attachment, you can get a static level of bright lines in the laser rotary head, the SJ3 type equipped with detectors, the charge , connectors, suspension, laser target, and other accessories. The computer connected to receiver of  green laser pointer  should be connected to the projector.
Blister-type optical leveling, swinger spirit level, which means that the laser plane level error depends on the accuracy of spirit level. If the instrument is lying down, according to the vertical spirit level laser scanning a vertical plane. Automatic the Anping Laser swinger. Developed by Beijing Optical Instrument Factory SJZ1 type automatic the Anping laser swinger, belonging to the instruments of such works, which mainly use the vario-ray machine compensator, in order to achieve the purpose of automatically within the range of ± 10 'Anping it regardless of instrument tilt or not will always keep scanning the laser plane in the horizontal plane, so that the instrument is more suited to the environmental conditions, such as the vibration of the construction site.  green laser pointer  can be used in different locations for different purposes.
The main structure of the instrument shown in Figure 3.24-type light-emitting diodes one issued by the laser through the hanging hanging by a thread of the lens, through the motor driven rotating pentagonal prism to scan the full range of levels of laser datum. Electronic circuit in the instrument, you can change the motor speed and achieve the purpose of continuously variable transmission. Figure 3.24 Automatic Anping laser swinger chart. Compensation works: set the instrument axis to deviate from the plumb line angle (Figure b), a value for the deviation between the plumb line in the main surface of the lens portion of the position of the lens optical center O position, the value: in order to make the laser beam is always maintained in the vertical direction, the compensation mechanism of the instrument must be made material by the mirror light heart O automatically move to the point, so that the optical axis and the plumb line overlap, this time we can guarantee the swinger The laser beam is always in the vertical direction, that is, to achieve the purpose of automatic compensation. The manufacture can customize this kind of green laser pointer  for the better use of the customer.It is because of good and high quality and performance of  green laser pointer
