No matter dot measuring work is processing at close or long distance, under operation of night version illumination, it makes good job with long wavelength made 980nm infrared laser diode module within 100mW to 500mW. It keeps work with intense and powerful IR laser light emission from a IR laser diode. Only after its proper use of night version device and 5V, 9v 1000mA DC power supply, it assures efficient conversion of clear and accurate infrared dot projection in long lasting use.
This infrared dot laser alignment applies different dimension metal housing tube, within freely installed distance of 3 meters, it just enables easy installation, and highly stable IR dot projection within 8 to 10 hours. According to correct use of output power and proper adjustment of both laser beam focus and IR dot emitting direction, not relying on manual labor force input, it brings users low price and long lasting IR dot alignment for IR laser sight, surveillance, intelligence system, optical instrument and high tech etc.
