No matter dot aligning work is processing at long distance or long time, not simply relying on a simple blue laser pointer, it makes better job with a DC power made 445nm blue laser diode module. Employed by an import 445nm blue laser diode within 50mW to 100mW and cooling system, this direct diode emission made laser device achieves superior nice thermal emitting and increasing stability blue dot alignment in continuous use. 
Only after easy installation onto industrial device, this 445nm blue laser diode module makes sure of constant and easy reaching blue laser beam and blue dot indication in continuous use. After passing through up to 24 hours beam stability and aging preventing test, and correct use of output power, it brings users high precision and long lasting dot indication for both industrial and high tech precise dot measuring fields effectively.
Applications: industrial precise dot alignment, laser show, laser displaying, laser communication, high tech and lab experiment work etc
