Under quite special use of highly clear and accurate dot alignment at quite long work distance, not workable at all to only rely on manual dot projecting device or simple laser pointer, it is just a quite nice solution to make advanced use of Berlinlasers 445nm 50mW blue laser diode module. It gets advanced use of import 445nm blue laser diode and inner cooling system, this durable structure made blue dot laser makes sure of increasing beam stability and highly clear blue dot projection in continuous use.
After advanced use of glass coated lens and special part of glass window in front of laser beam aperture, 445nm 50mW blue laser diode module projects high transmittance blue laser light and highly clear blue reference dot at quite long work distance. It gets even better thermal emitting than simple blue laser pointer. When it gets easy installation and adjustment of both laser beam focus and blue dot targeting direction, this blue dot laser achieves the most precise dot alignment for all great distance and formal lighting occasions effectively.
