Good Beam Stability 445nm 50mW Blue Dot Laser Alignment

In order to make highly clear dot measurement at long work distance, it is far more enough to reach with a simple blue laser pointer, but making good job with a 445nm 50mW blue dot laser alignment. It is not as bright as a 473nm blue DPSS laser, owing to its basic use of metal heat sink cooling system and APC, ACC driving circuit board, after proper use of 16mm diameter metal housing tube, this blue laser module just assures high stability blue dot projection in distance. Within freely installed distance of 3 meters, it makes sure of no barrier, no mistake and no mistake blue dot projection at long work distance perfectly.
