When users are trying to make highly clear line alignment under night vision work fields, it is not helpful at all until selecting quite professional device, such as Berlinlasers 980nm infrared line laser module. It is generating invisible infrared laser light and IR reference line from laser beam aperture. According to quite easy equipment with night vision device, such as a CCD camera, black and white camera or infrared laser camera , it is making immediate and highly clear infrared reference line alignment for any night vision fields effectively. This long wavelength 980nm infrared line laser module is used as an accessory part. Owing to beginning power within 5mW to 400mW and up to 80% photoelectric ability, it is generating high intensity infrared laser light from laser beam aperture and producing highly clear infrared reference line as long as 100 to 1000 meters in use. Under proper selection of output power and optic lens degree, together with high attention to intense and powerful thermal energy, this infrared line laser assures high security line alignment for military targeting, laser medical therapy, surveillance and intelligence system etc. http://www.berlinlasers.com/980nm-infrared-line-laser-module
