In order to make sure of highly precise dot measurement for all night version illumination fields, no matter it is pointing at close or long distance, it makes good job with long wavelength device of Berlinlasers 808nm infrared dot laser alignment. It applies qualified glass coated lens and glass window inside durable metal housing tube. Within constant work time of 8 to 10 hours, it just maintains highly stable performance and highly clear IR dot projection in long lasting use.
Being made with qualified glass coated lens and glass window inside highly durable anodized aluminum alloy housing tube, within freely installed distance of 3 meters, this infrared laser diode module enables easy installation, quick reaching and highly stable infrared dot projection. Only after correct use of output power, it keeps work with constant output power and electric current supply, and the most reliable IR dot measurement for military targeting, intelligence system, laser medical therapy, optical instrument and optical spectrum analysis etc.
