When night version line aligning work is processing constantly, it makes good job after the use of a long wavelength made device of 980nm infrared laser line generator. It is emitting invisible infrared laser beam directly from 980nm infrared laser diode. Only if it makes proper use of a night version device and selects a correct operating voltage AC/DC adapter, it assures continuous infrared laser beam emission, and highly clear IR line alignment under all night version fields effectively. The genuine line alignment with 980nm infrared laser line generator is continuing for quite long time, and also maintaining highly stable IR line projection. The advanced use of separate crystal lens assures highly uniform and fine infrared reference line projection, but also gets no laser light decay or blur. It should be selecting with correct output power and optic lens degree, after its proper mounting onto night version device, this 980nm infrared laser module makes no mistake and no track IR line alignment constantly. Technical data: Item: Berlinlasers 980nm infrared laser line generator Output power: 100mW-500mW Laser class: IIIb, IV Optic lens: 10-93 degree separate crystal lens Adjustable focus: yes Applications: military targeting, infrared laser sight, laser medical therapy device, and scientific research work etc http://www.berlinlasers.com/980nm-separate-crystal-lens-infrared-laser-line-generator
