When dot measurement work is processing at various work distances, not relying on a simple green laser pointer, it makes even better job with a 515nm green laser diode module within 5mW to 50mW. It projects highly visible forest green laser beam at several miles. Being made with good cooling system, within constant dot measurement of 8 to 10 hours, it achieves good laser beam stability and highly clear green dot projection in long lasting use.
This 515nm green dot laser applies different dimension metal housing tube. After easy connects with 5V, 9V 1000mA DC power supply, it assures constant forest green laser beam emission, and highly clear green dot projection within long extending distance of 25 meters. When it makes correct use of output power and freely adjusted dot diameter, it brings users high accuracy and high stability dot alignment for military dot positioning, laser marking, laser engraving, drilling system and high tech work etc.
