Quarton Green Line Laser Module, 520nm, 7~10VDC, Class 1, Fan Angle >120°, 1~20 meters work distance, VLM-520-37 LPT, Professional Use Applications

• Professional Green Straight Line Laser Module, ultra-precision grade for professional leveling, alignment, adjusting, positioning, measuring and targeting device. Laser line accuracy: 20" (+/- 1mm @10m). Emitting angle:> 120°. Operating Voltage: 7~10 VDC operation. Dimensions: (W)14 x (H)14 x (L)26 mm ( D0.551 x 1.023 inches).
• Wave length: 520 nm. Laser power output: Class I – less than 0.39mW. (Update 2/25/2021 - The laser output (the brightness) is exactly the same as before. The reason why the Laser Class is changed now is that, according to the latest IEC 60825-1 regulations, the output is measured by 7mm aperature stop at the position of 10cm. Therefore, you see that its Class is changed from "Class II" to "Class I" now, even though the brightness is exactly the same as before.)
• Direct Green Laser Diode for large temperature operation range. The supreme line-accuracy and the widest emitting angle line Laser module for use with Professional applications. Versatile mechanical structure on 4 sides, easy to fixed. Please notice: laser modules are not supposed to be sold with any power source, power supply, base for plugging, or wiring terminals. Because modules are simply components, and it means that you have to wire it to your own power source by yourself.
• Laser beam is focused at 10 meters to generate best thin laser line from 5 meters to 20 meters. This module has integrated quartz cylindrical lens, collimating lens, laser diode, and APC driver circuit. APC driver circuit enables the Laser output power safe and constant.
• Notice: Our laser modules are NOT laser pens and are NOT intended for general commercial or consumer use like standard laser pointer. They feature NO built-in switch or battery compartment and must be operated with an external power supply or battery holder.
