High Tech Field Used Berlinlasers 100mW 445nm Blue Laser Diode Module What is an efficient job to make ultra clear and precise dot indication at various work distances? A short wavelength made 445nm blue laser diode module would be a quite nice solution to get ideal dot alignment accuracy as expected. It applies 445nm blue laser diode as beam emitting source, integrating with cooling system inside a durable metal housing tube, it enables good heat dissipation and longer time lasting blue dot projection stably. Connected with 5V 1000mA DC power supply, not spending extra time on battery change, laser diode module enables long time lasting blue dot projection within 10 hours per day, without effect by overheating and over current impact as well. It is easily installed or integrated with industrial device, after its freely adjusted laser beam focus and dot emitting direction within three dimensions, it brings users excellent dot alignment experience for all precise machinery processing works effectively. Applications: industrial precise device manufacturing, laser marking, laser engraving, drilling system, laser communication, laser show, high tech https://www.berlinlasers.com/445nm-blue-laser-diode-module
