Good Direction Berlinlasers 808nm Infrared Laser Diode Module In process of highly precise and clear dot alignment for all night version fields, it is operating easy and quick with a long wavelength made Berlinlasers 808nm infrared laser diode module within 100mW to 400mW. After the use of 5V, 9V 1000mA DC power supply, not spending time on alkaline battery power source, it is generating high intensity and highly powerful infrared laser light, but also projecting highly clear infrared dot alignment within constant work time of 8 to 10 hours. This infrared dot laser applies a qualified glass coated lens and glass window, configured with 16mm and 26mm diameter metal housing tube, this infrared laser diode module enables easy installation, high transmittance IR laser light emission and highly clear infrared dot alignment at various work distances. When it gets correct use of output power and easy mounting onto night version device, it assures no mistake measurement for infrared laser communication, military targeting, laser medical therapy and night hunting work etc. https://www.berlinlasers.com/808nm-infra...er-diode-module
