Adjustable Focus Lens 515nm Green Laser Diode Module


No matter dot measuring work is processing at close or long distance, not the same as a simple green laser pointer, it makes even better job with a 515nm green laser diode module. It gets constant power source from 5V, 9V 1000mA DC power supply. Combined with an import 515nm green laser diode and metal heat sink inside different dimension metal housing tube, it enables superior nice thermal emitting and highly stable dot indication in continuous use.
Being with a qualified glass coated lens and glass window inside durable metal housing tube, after up to 24 hours beam stability and aging preventing test, this 515nm green dot laser is performing well with high transmittance green laser light emission and highly reliable green dot projection under moisture or dust as well. Within long extending distance of 25 meters and multiple lighting occasions, it achieves high accuracy and low cost dot projection for military targeting, drilling system, laser marking, laser engraving and high tech work etc.
