In order to make highly clear and accurate dot measurement at different work distances, it is making good job with a direct diode made Berlinlasers 515nm green laser diode module. Available with import 515nm green laser diode within 5mW to 50mW, and metal heat sink cooling system, it gets increasing laser beam stability and highly clear green dot projecting in long lasting use.
After correct use of output power and easy mounting onto industrial device, within freely installed distance of 3 meters, this 515nm green dot laser makes sure of highly clear and easy reaching of green dot onto any raw material surface. Within the maximum work distance of 25 meters, it assures good dot aligning result for laser marking, laser engraving, drilling system and high tech work etc.
