Glass Coated Lens 808nm Infrared Laser Line Generator Whatever kind of working surface users are trying to make highly clear line alignment, it is not workable at all to rely on any visible laser device, but making even better job with a long wavelength device of 808nm infrared laser line generator. It is projecting intense and powerful infrared laser light from a 808nm infrared laser diode. Cooperating with night version device and 5V, 9V 1000mA DC power supply, it keeps work with constant infrared laser beam and infrared line projection at various work distances. After advanced use of qualified glass coated lens within 10 to 110 degree, after strict laser beam stability tests up to 24 hours, this infrared line laser module is generating highly straight and fine infrared line within various line lengths. It enables the maximum installed distance of 3 meters. After correct use of output power and optic lens degree, and freely adjusted infrared line fineness, it assures no mistake and no barrier line alignment for night hunting, infrared laser sight, military targeting, laser medical therapy and high tech work etc. https://www.berlinlasers.com/808nm-glass...-line-generator
