Whatever kind of working surface it is in need of highly precise line measurement under all night version illumination fields, it makes good job with a long wavelength made Berlinlasers 980nm infrared line laser alignment. It projects invisible IR laser beam directly from a 980nm infrared laser diode. Designed with qualified glass coated lens or separate crystal lens within 10 to 110 degree and special use of a glass window inside highly durable metal housing tube, it assures high linear quality and highly straight IR laser line projection within various line lengths. After its freely adjusted laser line fineness, it assures high level of accuracy IR line measurement for IR laser sight, intelligence system, laser medical therapy, infrared laser communication and high tech etc.
