If high precision line projection is processing under night vision fields, it is a quite efficient method to try Berlinlasers 980nm infrared line laser alignment. It employs import 980nm infrared laser diode as beam emitting source. Owing to its invisible infrared laser beam and IR reference line projection from beam aperture, only after professional equipment with night vision device and external DC input power supply, infrared laser module makes efficient infrared laser light conversion and highly clear IR line projection immediately. Employing import 980nm infrared laser diode within 100mW to 500mW, infrared line laser alignment is designing with 16mm or 26mm diameter tube on basis of real output power. It leaves quite larger space for inner metal heat sink cooling system and APC driving circuit board. It should pass basic measurement and experiment, after correct selection of output power and fan angle, IR laser module achieves high precision and high speed IR line indication in distance perfectly. Technical data: Item: Berlinlasers 980nm infrared line laser alignment Output power: 100mW-500mW Laser class: IIIb, IIV Fan angles: 10-110 degree glass coated lens, separate crystal lens Adjustable focus: yes Applications: infrared laser sight, military targeting, night hunting, surveillance etc http://www.berlinlasers.com/980nm-infrared-line-projecting-laser-alignment
