In process of those of highly precise and accurate dot alignment in those of night version fields, not the same as a simple infrared pointer, it is making even better job with a long wavelength device, such as a long wavelength made device, such as a 980nm infrared laser diode module. It is projecting invisible infrared laser beam from beam aperture, thus it is always working with night version device. It should be selecting with correct output power, within the maximum installed distance of 3 meters, this infrared dot laser makes sure of high precision and high accuracy infrared dot alignment for military targeting, intelligence system, night hunting, laser medical therapy device and other night version fields etc.
