In various precise dot measuring work at various work distances, with the assistance of a 515nm green dot laser alignment and DC power supply, it enables constant forest green laser beam emission at several miles. Besides its close distance dot projection, it also assures highly clear green dot projection within long extending distance of 25 meters and formal lighting etc.
Being made with 16mm and 26mm diameter metal housing tube, together with electric wires, this 515nm green laser module enables freely installed distance of 3 meters, easy and quick reaching of forest green dot projection in continuous use. It allows constant dot measurement within 8 to 10 hours. When it makes correct use of output power and freely adjusted dot diameter, it just achieves high accuracy, high efficiency dot projection for drilling system, industrial precise dot alignment, laser marking, laser engraving and high tech etc.
