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

In any type of high precision and high stability dot alignment, it should be the most preferred job for users top operate a Berlinlasers 650nm red dot laser module. It keeps work with intense red laser beam emission from a 650nm red laser diode within 5mW to 100mW. The basic use of a metal heat sink cooling system is configured with 16mm and 26mm diameter anodized aluminum alloy housing tube, it enables easy carrying, good thermal emitting and highly reliable red dot alignment in long lasting use. 
Owing to the special use of APC, ACC driving circuit board, available with wide range output power of 5mW to 100mW, this 650nm red dot laser module is performing well with constant output power and electric current supply. It gets reduced possibility of tube burning out or damage. According to correct use of output power and proper adjustment of red dot diameter, it is able to provide users excellent dot aligning solution for all precise device manufacturing work fields effectively.
Applications: drilling system, laser marking, laser engraving, red laser sight, laser medical therapy and treatment, high tech etc
