Unless the use of any prior dot positioning work, in order to make highly clear dot measurement for all night version fields, it always makes a good job to operate a long wavelength made Berlinlasers 808nm infrared laser diode module. It keeps work with intense and powerful infrared laser beam emission directly from a 808nm infrared laser diode. Only after its professional equipment with other night version device, it enables High efficiency conversion of clear and accurate infrared dot alignment at long extending distance. 
Only after its easy connects with DC power supply and cooperating with good thermal emitting system, this infrared laser diode module makes constant IR laser beam and IR dot indication in continuous use. It enables high stability IR dot projection within 10 hours. It gets no effect by increasing temperature, but maintains up to 85% laser beam stability. When users are paying high attention to laser safety issue and avoiding eye exposure to laser beam aperture, it brings users easy and secured dot indication in long lasting use.
Applications: infrared laser sight, laser medical therapy, military targeting, night hunting, surveillance and high-tech
