In process of accurate line alignment under night vision, nothing can be observed by human eyes directly. However, laser tech engineer has just developed a quite practically used device, such as 808nm infrared line laser alignment. When it is generating invisible infrared laser beam directly from 808nm infrared laser diode, equipped with night vision device, such as CCD camera, black and white camera or infrared laser camera, this infrared dot alignment device is just making quite convenient and accurate IR dot generation under all night vision illumination work fields effectively.
In some of special work field, such as military targeting, surveillance or intelligence system etc, 808nm infrared line laser alignment would be applied at quite long work distance. It is getting selected power within 5mW to 400mW. Not the same as formal visible laser devices, this long wavelength 808nm infrared laser module is not only generating invisible IR laser beam from beam aperture, but also keeping quite high photoelectric ability of up to 80%. The practical IR line aligning work is applied at even longer distance in use. For instance, in occasion that it is selected within high power of 200mW to 400mW, infrared laser line aligning work can be processed at longer distance of 100 to 1000 meters in use.
Whatever kind of working surface, 808nm infrared line laser alignment is only used as an accessory part, but not able to be used separately. It is selecting qualified glass coated lens or separate crystal lens. On basis of desired line length in use, users can make free selection of optic lens degree within 10 degree to 110 degree. IR alignment laser line is keeping quite high linear quality. When it is passing through quite strict beam stability tests up to 24 hours, this laser line generator obtains superior nice laser light cycling use and highly stable IR line projection in continuous work easily.
In any night vision line aligning work, 808nm infrared line laser alignment would have to work for quite long term, while still maintaining extremely stable performance in use. Owing to excellent use of APC, ACC driving circuit board, under super rapid temperature increasing of laser module tube, this alignment laser makes sure of the most efficient preventing of electric current impacting, and then achieving the most stable IR line projection within daily operating time of 8 to 10 hours. Whenever it is beginning to work, users can never see any IR light directly, it is the most important issue for user to wear 808nm infrared laser safety goggles, and then obtaining free and no mistake line projection perfectly.
