Low Price 50mW 650nm Red Dot Laser Module
In order to make clear and accurate enough dot alignment at quite long work distance, it always makes good job with the assistance of a 50mW 650nm red dot laser module. It is an industrial stabilized dot measuring tool. The special use of import 650nm red laser diode and metal heat sink cooling system have assured at least 40% improvement of laser beam stability, and highly clear red dot projection in long time use.
The basic use of AC/DC adapter assures constant red laser beam and red reference dot projection from beam aperture.
