Under quite special application field of night vision, it should be efficient solution to make clear cross line measurement with a Berlinlasers 808nm infrared cross laser alignment. It is generating invisible IR laser beam from beam aperture. When it is operating as an accessory part, after easy use of a DC input power supply, it keeps work with high photoelectric ability IR laser light emission and highly clear IR cross line generation in distance. This 808nm infrared cross laser alignment selects qualified glass coated lens with different fan angles, which generates different dimension IR cross line source in use. The special use of glass window in front of laser beam aperture prevents any moisture or dust in use. It should get correct selection of fan angle and output power, after simple screw of adjustable focus optics, infrared laser module makes the most precise IR cross line generation in all night vision fields effectively. Technical data: Item: Berlinlasers 808nm infrared cross laser alignment Output power: 100mW, 200mW, 300mW, 400mW, 500mW Laser class: IIIb, IV Fan angles: 10, 15 and 110 degree glass coated lens Power source: 5V, 9V 1000mA DC input power supply Applications: military targeting, night hunting, intelligence system, surveillance etc http://www.berlinlasers.com/980nm-infrared-cross-projecting-laser-alignment
