In order to make highly precise and accurate dot measurement for those of night version application fields, it is not easy to reach with any visible laser device or other manual dot projecting work at all. At the same time, after constant technical innovation of 980nm infrared laser diode tech and a qualified glass coated lens, it is being made into a quite practically used device of infrared laser diode module. Owing to its invisible infrared laser beam emission from beam aperture, only after its proper equipment with night version device and external electric power source, it makes sure of high precision and highly clear IR dot generation at various work distances.

Designed with an import 980nm infrared laser diode, not the same as an infrared laser pointer only used for temporary dot positioning work, the genuine use of a 980nm infrared laser diode module is just working for quite long time. Cooperating with a metal heat sink cooling system, this direct diode emission made IR laser device gets increasing laser beam stability of at least 40% in continuous use. In formal constant IR dot projection work within 8 to 10 hours, after leaving enough space for tube cooling down, it achieves high level of laser light cycling use, and highly reliable IR dot projection for multiple night version precise dot measuring works.

After easy connects with an AC/DC adapter, not spending extra time on battery change, this 980nm infrared laser diode module is working well with constant infrared laser beam emission. When it gets wide range output power of 100mW to 500mW, equipping with a qualified glass coated lens and glass window in front of laser beam aperture, this infrared dot laser is working well with high photoelectric ability infrared laser light emission, and converting into extremely clear and accurate IR dot generation at great distance of 100 to 1000 meters.

On the basis of APC, ACC driving circuit board, whatever output power it is selecting, this 980nm infrared laser diode module is working well with constant output power and electric current supply. In those of long lasting night version precise dot measuring works, it enables good performance under increasing temperature and serious electric current impact, and long serving lifetime of more than 8,000 hours. When infrared alignment laser gets correct use of output power and freely adjusted dot diameter, after correct wearing of laser safety goggles and avoiding eye exposure to beam aperture, it achieves easy and secured use in long lasting use.
