In any special working occasion of night version illumination, it is making efficient job with a long wavelength device, such as an 808nm infrared laser diode module. It is only operating as an accessory part, which is working with night version device, such as a CCD camera, black and white camera or infrared laser camera. After correct use of 5V, 9V 1000mA DC power supply, a correct output power made infrared dot laser enables easy installation, good direction and easy reaching infrared dot alignment for military targeting, night hunting, infrared laser sight, laser medical therapy, and intelligence system etc.
