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

Different from a simple red laser pointer used for temporary dot positioning work, the real use of a Berlinlasers 650nm red laser diode module has just provided users quite special dot alignment solution for those of long time and long distance use. Employed by an import laser diode and thermal emitting system inside a durable metal housing tube, it enables good laser beam stability and long lasting red dot projection in continuous use.
This laser diode module passes through up to 24 hours beam stability and aging preventing test. It only allows proper use by skilled users or professionals. According to correct use of output power and freely adjusted red dot diameter, it enables highly concentrated red laser light source emission and increasing accuracy and brightness red dot projection at long extending distance effectively. 
Applications: drilling system, laser marking, laser engraving, red laser sight, laser medical therapy and high tech
