In order to get clear enough dot measurement under night vision work fields, without the use of formal visible laser devices, it would be greatly helpful choice to use Berlinlasers infrared dot laser alignment. Employed by long wavelength 808nm infrared laser diode, owing to its quite high photoelectric ability up to 80% and direct diode emission, this infrared laser module is just achieving quite intense infrared laser light emission and highly clear infrared reference dot projection in distance easily. Designed with wide range output power of 5mW to 400mW, equipped with inner metal heat sink cooling system and APC, ACC driving circuit board, this infrared dot laser alignment is keeping work with highly intense infrared laser beam and the most stable infrared reference dot projection as long as 100 to 1000 meters in use. Within freely installed distance of 0.3 meter to 3 meters, this infrared laser module ensures the most satisfied dot positioning results for military targeting, laser medical therapy, surveillance and intelligence system etc. http://www.berlinlasers.com/high-power-808nm-infrared-dot-laser-alignment
