Until the time users are trying to make ultra clear dot indication for a quite long time, not relying on a simple green laser pointer, it is a better substitute to operate a 5mW 532nm green dot laser alignment. Employed by a middle wavelength 532nm green DPSS laser system, owing to its low laser beam divergence and special TEM00 laser beam mode, it enables high brightness green laser light source emission and highly clear green dot projection for inner room and close distance dot positioning work.

After quite easy use of a 5V, 1000mA DC power supply, this 16mm diameter metal housing tube made green alignment laser makes sure of constant green laser beam and green dot projection. It allows long lasting dot indication within 8 to 1 hours, without light decay or blur in continuous use. After easy screw of adjustable focus optic lens, it gets highly concentrated green laser light source and increasing accuracy green dot indication for all material processing works effectively.

Applications: industrial machinery processing, drilling system, laser marking, laser engraving, high tech and lab experiment

In process of high precision and high stability dot projection at long extending distance, not easily to reach with a laser pointer, the creation of Berlinlasers 532nm green dot laser module is a better substitute to make long lasting and long distance green laser beam and green dot projection in distance. Employed by a metal heat sink cooling system inside a high duration metal housing tube, it enables easy carrying, superior nice thermal emitting and increasing stability green dot projection in continuous use.
Employed by a qualified glass coated lens inside different dimension metal housing tube, this dot laser module also passes through up to 24 hours beam stability test and aging preventing test. It achieves high precision green dot projection within the maximum work distance of 25 meters and high lighting. Only if it makes correct use of output power and proper adjustment of laser beam focus, it brings users the best dot alignment experience for all working occasions effectively.
Applications: drilling system, laser marking, laser engraving, military targeting and lab experiment

If users are not much sure of how to make ultra clear dot indication at long work distance, it just makes a good job with a Berlinlasers 50mW to 100mW blue dot laser alignment. Being made with an import 445nm blue laser diode inside 16mm diameter metal housing tube, after passing through up to 24 hours beam stability test and aging preventing test, it achieves high density blue laser light emission and ultra clear blue dot projection at long extending distance constantly.
After quite easy connects with 5V, 9V 1000mA DC power supply, this alignment laser makes high speed and quick response blue laser beam and blue dot projection at long extending distance. It gets no need to rely on any manual labor force input. Any time it makes correct use of output power and proper adjustment of laser dot diameter, within the maximum work distance of 25 meters, it brings users the best direction and the longest lasting dot indication for all machinery processing works effectively. 
Applications: industrial device manufacturing, laser show, laser displaying, laser communication, optical instrument and high tech
