In order to get quite accurate dot generation under night vision illumination work fields, unless the operation of any visible laser device or other manual dot targeting tool, it would be quite nice solution for users to adopt a quite long wavelength emitted 980nm infrared laser diode module. It is a quite long wavelength laser dot measuring tool. Owing to its emission of invisible IR laser beam emission from beam aperture, after its operation with night vision device, such as CCD camera, black and white camera or infrared laser camera, this IR laser alignment tool makes sure of highly clear and accurate IR dot projection in distance effectively.
Not the same as any visible laser devices, when 980nm infrared laser diode module is used for constant dot aligning work, it is projecting totally invisible IR light to human eye, which cannot be used separately, but just being used as an accessory part of night vision devices. For instance, different from formal dot printing device, this long wavelength designed IR laser is applied for quite different work places, such as surveillance, intelligence system, laser medical treatment device and other night vision illumination fields etc.
Under night vision, dot alignment work is processed at quite long work distance than formal laser devices. This 980nm infrared laser diode module is available with wide range power of 5mW to 500mW. Owing to its high photoelectric ability of up to 80%, this infrared laser is generating the most intense and powerful IR light emission, and then obtaining highly clear and accurate dot generation at extremely long distance of 100 meters to 1000 meters in use. After the selection of high power 980nm infrared laser up to 200mW to 500mW, it will make highly clear IR dot projection at long distance up to 50mW.
When 980nm infrared laser diode module is being made with high duration aircraft used aluminum alloy housing tube, under operation of quite harsh working occasion, only if it is freely installed within 0.3 meter to 3 meters, it make sure of quite convenient IR dot generation on any vertical or horizontal surface effectively. On basis of the use of APC, ACC driving circuit board design, even though there is quite rapid temperature increasing and serious electric current impacting from laser module tube, this alignment laser just gets superior nice control of constant output power and electric current supply, and then achieving the most stable IR dot projection in long term use. In occasion that invisible IR light is generated from beam aperture, users should only remember to wear 980nm wavelength preventing laser safety goggles until achieving secured dot measuring results perfectly.
