What is an easy job to make highly clear dot measurement? It is processing out of hand reaching, not easy to reach with a simple blue laser pointer, but making even better job with a Berlinlasers 445nm 50mW blue laser diode module. It projects highly visible blue laser beam directly from a 445nm blue laser diode. Only after the use of 16mm diameter metal housing tube, and metal heat sink cooling system, it achieves superior nice thermal emitting, easy installation and highly stable blue dot projection in continuous use.
This blue laser diode module adopts 5V 1000mA AC/DC adapter, without spending extra time on battery change, it keeps work with constant blue laser beam emission. Unless it is pointing under sunlight, it enables highly clear dot indication with the maximum work distance of 25 meters. After its proper installation and adjustment of both laser beam focus and dot projecting direction, it assures no mistake use for all industrial dot alignment, laser show, laser displaying, and high tech work etc.
