In order to make highly clear dot measurement at a bit longer distance than formal hand reaching, it is not easy to reach with a simple red laser pointer, but substituting by Berlinlasers 50mW 650nm red laser diode module. It is projecting highly visible red laser beam directly from a 650nm red laser diode. After proper use of 9V 1000mA DC power supply, and good use of thermal emitting system, this red dot laser is working well with highly clear red dot alignment within the maximum work distance of 25 meters and other formal lighting occasions etc.
Being made with 26mm diameter anodized aluminum alloy housing tube and extending electric wires, this 650nm red laser diode module enables easy installation and highly stable red dot alignment in continuous use. According to easy installation and proper adjustment of both laser beam focus and red dot emitting direction, this red dot laser assures the lowest price, the most stable red dot alignment for all industrial precise dot measuring work fields perfectly.
