Under any working occasion where users are trying to make highly clear line alignment under night vision, not easily relying on manual or mechanical line aligning works, however, it is substituting by long wavelength made 980nm infrared line laser module. It projects invisible infrared laser beam from beam aperture. Owing to its invisible infrared laser beam and IR line projection, after special use of night vision device, it makes efficient infrared laser light conversion and highly clear infrared line projection under all night vision fields. After simple use of external DC input power supply and special use of electric wires extension for both 980nm infrared line laser module and DC power source, it is keeping work with continuous IR line projection and good protection of tube from overheating and over current in continuous use. After quite easy adjustment of laser beam focus and IR line targeting direction, a correct output power and optic lens degree made IR laser line generator makes no mistake line alignment perfectly. Technical data: Item: Berlinlasers 980nm infrared line laser module Output power: 5mW-500mW Laser class: IIIa, IIIb Optic lens: 10-110 degree glass coated lens, Powell lens Applications: night hunting, infrared laser sight, military targeting, laser medical treatment http://www.berlinlasers.com/uniform-980nm-infrared-line-laser-module
