In order to get the most precise line alignment at great distance, it should be your best choice to adopt 100mW green laser line generator. It adopts the most advanced 532nm green DPSS laser tech, owing to its low laser beam divergence and quite special laser beam mode of TEM00, it projects highly fine and straight green reference line at great distance easily. In addition, after quite easy screw of laser beam focus lens, green laser module enables easy adjustment of line thickness until achieving the most satisfied measuring result. Designed with external DC power supply, 100mW green laser line generator keeps work with continuous green laser beam and green line continuously. It is not affecting by overheating and over current. In addition, the special use of APC, ACC driving circuit board is protecting green laser module from any possibility of laser tube burning out or damage. Only after continuous work within 8 to 10 hours and proper installation onto industrial device, it makes high precision and high efficiency line alignment perfectly.
