How to operate glass lens 532nm green laser diode module precisely

If you are looking for an easy operating and highly precise dot alignment at various work distances, different from a simple green laser pointer, it is operating easier with Berlinlasers 5mW to 100mW 532nm green laser diode module. It gets basic use of cooling system inside different dimension metal housing tube. It enables long lasting dot alignment within 8 to 10 hours, and no light decay or blur in real use.
On the basis of a qualified glass coated lens, whatever kind of working surface it is pointing, this 532nm green dot laser is working well with highly clear and accurate green dot alignment at various work distances. Only after its easy installation onto desired machine or device, within freely installed distance of 3 meters, it makes no barrier, no mistake and low cost dot alignment in all occasions perfectly.
Applications: laser marking, laser engraving, military targeting, drilling system, lab experiment and high tech etc
