In order to make highly clear dot generation under night version illumination, it makes good job with a long wavelength made device of Berlinlasers 980nm infrared dot laser alignment. It is operating easy with night version device and 5V, 9V 1000mA AC/DC adapter. Only after its correct use of output power, within freely installed distance of 3 meters, it makes sure of high precision and good direction IR dot projection for infrared laser communication, military targeting, laser medical therapy, night hunting and surveillance etc.
