In order to make highly clear dot alignment under all night version fields, it is not easy to reach with any visible laser device, it always makes sure of high efficient dot measurement with a long wavelength made device of 808nm infrared laser diode module. It applies an import 808nm infrared laser diode within 100mW to 400mW, equipping with a metal heat sink cooling system and qualified glass coated lens, it is working well with high transmittance and high photoelectric ability infrared laser light emission, and highly clear infrared dot alignment at various work distance. Only if it makes proper use of night version device and gets constant power source supply, this 808nm infrared dot laser always makes sure of high precision and high accuracy IR dot generation for military targeting, surveillance, intelligence system, laser medical therapy and night hunting work etc.https://www.berlinlasers.com/808nm-infrared-laser-diode-module
