Under operation with ultra clear and accurate dot projection at a long extending distance, it is not simply relying a green laser pointer, but substituted by a 532nm green dot laser module. It emits the brightest green laser light from a middle wavelength 532nm green DPSS laser system. Owing to its low laser beam divergence and special TEM00 laser beam mode, it enables the brightest green laser light source emission and the most precise green dot projection at different work distances. 
Only after its easy connects with 5V, 9V 1000mA DC power supply, this dot laser module enables long lasting green laser beam and green dot projection within daily operating time of 10 hours. Being made with APC, ACC driving circuit board, it assures long lasting dot indication and no tube burning out or damage. It always brings users the best direction, the longest lasting and the most precise green dot alignment for all precise machinery processing works continuously.
Applications: drilling system, laser marking, laser engraving, laser medical therapy, scientific experiment and high tech
