In order to get the lowest prices dot alignment solution, once it is pointing at quite long work distance or other formal lighting working occasion, it is making good job with an intense beam emitting tool, such as a 445nm blue laser diode module. It projects moderate brightness blue laser light directly from a 445nm blue laser diode up to 50mW to 100mW.
Being made with the best quality glass coated lens and special use of glass window, once it is operating by skilled users or professionals, this 445nm blue laser diode module is working well with high transmittance blue laser light, and highly clear blue dot alignment under moisture or dust. Every time it makes correct use of output power and proper mounting onto industrial device, within freely installed distance of 3 meters, this blue dot laser assures low price, long lasting and high stability dot alignment for laser show, laser displaying, drilling system, decoration and high tech work etc.
