When high precision dot alignment work is processing at quite long work distance, not the same as a simple blue laser pointer, the unique use of a Berlinlasers 445nm blue laser diode module brings users quite special dot alignment experience for all precise machinery processing works. Being made with an import laser diode and thermal emitting system inside a durable metal housing tube, it is allowing quite easy operation, quick reaching and no mistake blue dot projection at long extending distance. This laser diode module applies a qualified glass coated lens and glass window inside a high duration metal housing tube. It passes through strict laser beam stability and aging preventing test up to 24 hours. It is generating high density blue laser light source and ultra clear blue dot projection as long as 25 meters. Any time users are obeying basic laser safety issue and avoid operation under sunlight, it brings users the best dot alignment experience for all machinery processing works effectively. Applications: industrial device manufacturing, laser marking, laser engraving, laser show, laser displaying, lab experiment https://www.berlinlasers.com/445nm-blue-laser-diode-module
