445nm Blue Laser Diode Module Any time users are not able to make quick response and good direction dot alignment at long work distance, it is just a very nice chance for users to apply a 445nm blue laser diode module. It keeps work with intense and formal brightness blue laser light directly from a 445nm blue laser diode up to 50mW to 100mW. It is an industrial stabilized dot measuring tool. Being made with a metal heat...
