Comparing with a simple green laser pointer only used for temporary dot positioning work, the adoption of a 532nm green laser diode module always makes sure of long lasting green laser beam and green dot projection from the laser beam aperture. The unique use of a metal heat sink and APC, ACC driving circuit board are cooperating well, which assures the most reliable green dot alignment and long serving lifetime in proper use. 
This laser diode module applies a qualified glass coated lens and glass window inside a high duration metal housing tube, which enables high transmittance green laser light source emission, and highly precise green dot alignment at long work distance. It bears various harsh occasion and wide range operating temperature as well. Within freely installed distance of 3 meters, not relying on any manual labor force input, a correct output power made laser device just brings users no mistake dot alignment in all application fields perfectly.
Applications: industrial machinery processing, laser marking, laser engraving, military targeting and scientific experiment etc
