In order to make ultra clear and precise dot projection at different work distances, it should be the best chance to operate a Berlinlasers 532nm green laser diode module. Employed by advanced 532nm green DPSS laser tech within 5mW to 100mW, cooperating with thermal emitting system and APC, ACC driving circuit board inside, it keeps work with constant green laser beam and green dot projection from laser beam aperture. It enables long lasting green dot projection within 10 hours, without any effect by overheating and over current in proper use.
Being made with a qualified glass coated lens and glass window inside a high duration metal housing tube, cooperating with up to 24 hours beam stability test, this laser diode module enables high density and high transmittance green laser light emission, and ultra clear green dot projection within great distance of 25 meters. After correct use of output power and proper adjustment of dot diameter, it brings users the highest level of accuracy dot alignment for all precise machinery processing works effectively. 
Applications: industrial machinery processing, drilling system, laser marking, laser engraving, optical instrument, high tech
