In various environmental and material testing works, either pointing at close or long distance, it would make an excellent job to apply a Berlinlasers 515nm green laser diode module. Employed by an import 515nm green laser diode and a qualified glass coated lens inside a high duration metal housing tube, only after its easy connects with DC power supply, it enables long operating time lasted green light source emission, converts into clear, precise and bright green dot indication in distance conveniently.

Cooperated with an AC/DC adapter, either pointing at close or long distance, laser diode module enables high stability and high accuracy green dot projection, allowing for freely adjusted laser dot diameter as as to achieve increasing accuracy measurement as expected. It always provides professionals good direction green dot alignment for thin film thickness measurement, surface flatness detection, and observation of material deformation and stress.
