How to make precise use of 515nm green laser diode module?

With the assistance of a Berlinlasers 515nm green laser diode module, either it is pointing at close or long distance, it makes a good job to operate a Berlinlasers 515nm green laser diode module. The advanced use of an import 515nm green laser diode and cooling system are configured with high duration metal housing tube, only after leaving enough time for tube cooling down, it achieves high level of laser light cycling use and highly reliable forest green dot alignment in continuous use. 
Employed by a qualified glass coated lens, this laser diode module also passes through strict laser beam stability test and aging preventing test up to 24 hours. It enables highly clear and precise forest green dot projection at long extending distances. When it users are selecting it with correct output power, after its freely adjusted laser beam focus and dot emitting direction, it achieves increasing accuracy and brightness green dot alignment at great distance perfectly.
Applications: drilling system, laser marking, laser engraving, lab experiment and high tech etc
