Highly Precise 980nm Infrared Dot Laser Alignment If users are getting serious need of clear and accurate dot measurement for all night version fields, it is operating easy and quick with a 980nm infrared dot laser alignment. It projects invisible and intense IR laser light from IR laser diode within 100mW to 500mW. After advanced use of a metal heat sink and durable metal housing tube, it achieves increasing laser beam stability and highly clear IR dot emission in long lasting use. This 980nm infrared laser diode module should only be working with night version device and 5V, 9V 1000mA DC power supply. Being made with electric wires, within freely installed distance of 3 meters, it assures easy reaching and no barrier IR dot projection onto any raw material surface. It provides users ideal infrared dot alignment solution for military targeting, laser medical therapy, intelligence system, surveillance, optical instrument and high tech etc. https://www.berlinlasers.com/980nm-infrared-dot-projecting-laser-alignment https://www.berlinlasers.com/980nm-infrared-laser-diode-module
