On the basis of constant technical innovation of 532nm green DPSS laser tech, laser tech engineer develops a high brightness 532nm green laser diode module within 5mW to 100mW. It projects the most visible green laser beam from a 532nm green DPSS laser. Being made with good thermal emitting and different dimension metal housing tube, it enables highly stable and accurate green dot projection in use. It provides users ideal dot aligning source for drilling system, laser marking, laser engraving, military targeting and high tech work etc.
