Once dot alignment is processed under night vision work field, it is just a quite hard job for users until getting a quite professional dot measuring tool. Instead of the use of simple sticker or pointer device, nothing can be observed under such working occasion. When laser tech engineer is developing a quite advanced dot alignment tool such as 808nm infrared laser diode module, after its proper equipment with a night vision device, such as a CCD camera, black and white camera or infrared laser camera, it is just effective enough to get constant infrared laser dot targeting result on various working surfaces effectively.
The real operation of 808nm infrared laser diode module is very special while comparing with other visible laser devices. It is employing 808nm infrared laser diode as its laser beam emitting source. When it is generating much longer wavelength than red laser device, this dot laser alignment tool should be used as an accessory part of night vision device, and then converting high intensity infrared laser beam into a highly accurate and clearly visible infrared laser dot on all desired working surfaces. According to quite easy adjustment of laser beam aperture part, infrared laser beam is focused, and then forming into the clearest dot instruction clearly and precisely.
When infrared laser diode module is applied for night vision aligning work, it can be used to make clear dot aligning for laser medical treatment, military targeting, surveillance and intelligence system etc. The real infrared laser dot alignment should also be processed at quite long work distance. Comparing with other visible laser devices, this infrared laser module is just available with quite higher output power until 400mW. Once infrared alignment laser dot targeting is processed at quite longer distance than 50mW, it would be selected with quite higher output power up 200mW to 400mW.
No matter what kind of dot alignment work field, this 808nm infrared laser diode module is operated as an accessory part, which is not able to be used separately. Its operation is keeping extremely high laser beam transmittance of up 80%, thus infrared laser beam is quite powerful and intense at quite long work distance up 100 meters to 1000 meters in distance. Whenever powerful and potential danger is caused by invisible infrared laser beam, users should remember to wear a pair of laser safety goggles, and then achieving high accuracy dot alignment effectively.
