Berlinlasers 515nm Green Laser Diode Module for Surveying and Engineering
Under operation of ultra clear and precise dot projection for both of surveying and engineers works, workers prefer to apply a Berlinlasers 515nm green laser diode module. It keeps work with intense green light emission directly from an import 515nm green laser diode, cooperated with APC, ACC driving circuit board, it enables high stability green dot projection for short-range layout, coaxial alignment of equipment, and point marking etc.
