If there is quite special need of highly clear dot alignment under night vision, it would not be workable at all to still use simple sticker, laser pointer or other mechanical dot measuring devices etc. None of light is observed by human eyes under such working occasion. However, under operation of long wavelength of high power 980nm infrared laser diode module, it is just emitting invisible infrared laser light and IR reference dot from beam aperture. When it is used as an accessory part of night vision device, after cooperation with CCD camera, black and white camera or infrared laser camera, this infrared dot laser is just becoming a real and the most practically used dot alignment tool for any type of night vision illumination work fields effectively.
On basis of quite mature and import 980nm infrared laser diode tech, laser tech engineer has just developed such high power 980nm infrared laser diode module, which should be perfect technical innovation for any night vision dot alignment work. When it is generating even longer wavelength than any other visible laser devices, this infrared dot laser cannot be used separately, but should be used under any night vision device. This infrared laser is keeping work with quite high photoelectric ability up to 80%, together with its import laser diode tech, within wide range output power of 600mW to 100mW, infrared dot projection can be processed at quite long distance.
In any type of night vision dot alignment work, high power 980nm infrared laser diode module can be used for multiple working occasions, such as military targeting, laser medical therapy, surveillance and intelligence system etc. When dot alignment is proceed under multiple working environments, high power 980nm infrared laser diode module gets the most durable structure of aircraft used aluminum alloy housing tube and inner copper made laser diode core part, which would make sure of superior nice thermal emitting and quite stable infrared laser dot alignment under any working occasion, including those of harsh occasion, such as mechanical shocking, calibration or moving etc.
Owing to specially designed electric wires extension for both high power 980nm infrared laser diode module and DC input power supply, usually within freely installed distance of 0.3 meter to 3 meters, it is just getting quite convenient installation and adjustment, and then achieving highly clear infrared reference dot on any vertical or horizontal surface immediately. No matter what kind of working surface it is pointed, human eyes cannot capture infrared laser beam directly, while still bringing serious hurt to human eyes. Only if users are avoiding eye exposure and remembering to wear infrared laser safety goggles, this alignment laser just achieves easy and clear dot alignment constantly.
