No matter dot measuring work is processing at close or long distance for those of night version illumination work fields, it is operating easy and quick with a long wavelength made device of Berlinlasers 980nm infrared dot laser alignment. It keeps work with intense and invisible infrared laser beam emission directly from a 980nm infrared laser diode. Not relying on any manual labor force input, after connects with 5V, 9V 1000mA DC power supply, it just assures long lasting IR dot projection.
Being made with qualified glass coated lens and glass window inside highly durable metal housing tube, this infrared laser diode module is keeping work with high quality IR laser light emission, and highly clear and stable IR dot projection under moisture or dust as well. Only after its correct use of output power and freely adjusted laser beam focus, it assures increasing accuracy infrared dot projection for IR laser sight, military targeting, intelligence system, infrared laser communication and high tech etc.
