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

Different from any other visible laser devices, in order to get ideal dot alignment accuracy for all night version fields, it should be a good choice to operate a long wavelength made device of Berlinlasers 808nm infrared laser diode module. Employed by an import 808nm infrared laser diode inside 16mm and 26mm diameter metal housing tube, after getting superior nice thermal emitting, it achieves ultra stable and reliable infrared dot projection in continuous use.
Cooperating with a qualified glass coated lens and glass window inside, the genuine use of a IR laser diode module achieves high transmittance IR laser light source emission, ultra clear and precise infrared dot alignment as long as 50 meters. It should only be selected with correct output power, within freely installed distance of 3 meters, it brings users the best direction and the longest lasting IR dot alignment for all night version fields effectively.
Applications: infrared laser communication,optical instrument, military targeting, laser medical therapy and high tech etc
