In various working occasions where users are in need to make clear dot alignment at various work distances, it is always a very efficient solution to try Berlinlasers 532nm green dot laser module. It makes advanced use of 532nm green DPSS laser tech, after basic use of metal heat sink cooling system and APC driving circuit board inside durable metal housing tube, it is achieving superior nice thermal emitting and extremely stable green dot alignment in continuous use. This 532nm green dot laser module is in need to make continuous dot alignment, without laser light decay or dim. The genuine use of glass coated lens makes cooperation with glass window in front of laser beam aperture, it is keeping highly clear green dot projection and stable dot measuring result, including harsh occasion of moisture or dust. After correct selection of output power and proper adjustment of laser beam focus, green laser alignment makes sure of high speed and high precision dot alignment in all occasions effectively.
