In process of the most precise line alignment under night vision, including both close distance and long distance, it is just a very nice solution to try Berlinlasers 808nm infrared laser line generator. It projects invisible infrared laser beam and IR reference line from laser beam aperture. When it is operating as an accessory part, after professional equipment with night vision device and easy connects with AC/DC adapter, it assures highly intense infrared laser beam emission and highly clear IR line alignment continuously. This 808nm infrared laser line generator employs qualified separate crystal lens. It keeps work with non Gaussian distribution infrared laser beam emission, and uniform IR reference line projection up to 85%. It should not only be selecting with correct output power and fan angle, after quite easy adjustment of laser beam focus, it achieves no mistake and no barrier IR line alignment in distance effectively. Technical data: Item: Berlinlasers 808nm infrared laser line generator Output power: 5mW-400mW Laser class: IIIa, IIIb Fan angles: 10-93 degree separate crystal lens Adjustable focus: yes Power source: 5V, 9V 1000mA AC/DC adapter Applications: military targeting, night hunting, surveillance, intelligence system etc http://www.berlinlasers.com/808nm-separate-crystal-lens-infrared-laser-line-generator
