What is the best job to make highly clear dot alignment? In order to make highly clear dot alignment at quite long work distance, not easy to reach with a simple blue laser pointer, it makes good job with Berlinlasers 445nm blue laser diode module. It applies import 445nm blue laser diode within 50mW to 100mW. After good use of a metal heat sink cooling system and 16mm diameter metal housing tube, it enables easy installation, good thermal emitting and highly stable blue dot projection in continuous use.

Available with a 5V, 9V 1000mA DC power supply, this blue dot laser is keeping work with highly visible blue laser beam and blue dot emission in distance. It allows the maximum installed distance of 3 meters, not limited by long distance, high height or hard reaching, it assures no mistake and no barrier dot alignment for laser show, laser displaying, laser communication and high tech etc.
