Until the time users are trying to make high precision dot alignment at various work distances, it just makes a good job to operate a Berlinlasers 515nm green laser diode module. The genuine use of an import 515nm green laser diode and metal heat sink cooling system are assuring increasing laser beam stability, and highly reliable forest green dot projection within constant work time of 10 hours. Owing to the unique use of a qualified glass coated lens and glass window inside a high duration metal housing tube, this laser diode module also passes through up to 24 hours beam stability test. It achieves high level of laser light cycling use, and highly clear green dot projection in continuous use. It keeps work with good dot aligning performance under moisture or dust. When it gets proper adjustment of laser dot diameter and dot emitting direction, without the use of sunlight, it just brings users no mistake dot alignment at great distance effectively. Applications: industrial precise machinery processing, drilling system, laser marking, laser engraving, military targeting and high tech
