In process of long lasting and high stability line measurement in all night version illumination fields, it is operating easy and quick with a long wavelength made Berlinlasers 980nm infrared line laser alignment. The advanced use of qualified glass coated lens and separate crystals within 10 to 110 degree inside metal housing tube assures high quality Gaussian or non Gaussian distribution IR laser light emission. After projecting highly straight and fine IR line within various line lengths, within freely installed distance of 3 meters, it assures high level of accuracy and high stability IR line projection for infrared laser sight, surveillance, intelligence system, infrared laser communication and lab experiment etc.
