If you are trying to make dot measurement under night vision, it is just the best chance for user to make good use of Berlinlasers 808nm infrared dot laser alignment. It is available with quite longer wavelength than formally used 650nm red laser device, which is generating invisible infrared laser beam in distance. Once it is workable for clear dot alignment, it is just working together with CCD camera, black and white camera, or infrared laser camera, and then forming into clear infrared dot instruction effectively.
808nm infrared dot laser alignment is not a separate part, but always workable as an accessory part. It is also getting different use from those of visible laser devices. This infrared laser module is workable for night vision illumination work fields, bringing users clear infrared laser dot targeting for night hunting, surveillance, intelligence system, military targeting and laser medical treatment device etc. Users should only be cautious enough with powerful infrared laser light and avoid eye exposure, and then getting secured IR dot positioning perfectly.
