If users are trying to make highly clear dot projection under night vision, long wavelength made Berlinlasers 808nm infrared dot laser module enables quite easy use after connect with a DC input power supply. It is generating invisible IR laser light and IR laser dot from beam aperture. When it is used as an accessory part, after proper equipment with a CCD camera, black and white camera or IR laser camera, this IR dot laser achieves highly intensity IR laser light and highly clear IR reference dot projection under night vision. This 808nm infrared dot laser module enables quite easy use for any night vision fields. It gets proper use of 808nm infrared laser diode within 5mW to 400mW, under basic use of inner cooling system inside aluminum alloy housing tube, it achieves excellent thermal emitting and super high laser beam transmittance. Every time users are making proper adjustment of laser beam focus and IR dot projecting direction, after correct selection of output power, this infrared dot laser achieves the most satisfied IR dot generation perfectly. Technical data: Item: Berlinlasers 808nm infrared dot laser module Output power: 5mW-400mW Optic lens: glass coated lens Adjustable focus: yes Electric power source: 5V, 9V 1000mA DC input power supply Applications: military targeting, laser medical therapy, surveillance, intelligence system, night hunting system http://www.berlinlasers.com/808nm-infrared-dot-laser-module
