What is a good solution to make sure of clear and fine line alignment in distance? It might not be easy to reach with simple manual line drawing or printing work. When laser tech engineer is making constant technical innovation of advanced 532nm green DPSS laser tech, equipping with a glass coated lens with different fan angles, it is being made into a quite practically use device of 532nm green line laser module. In practical precise and fine line generation onto various working surfaces, only after its correct use of output power and optic lens degree, it always brings users easy reaching and good direction green reference line projection onto a lot of raw material surfaces. This 532nm green line laser module gets constant power source supply from a 5V, 9V 1000mA DC power supply. It is totally different from a green laser pointer. Not any longer limited for the temporary positioning works, it gets even better thermal emitting. The adoption of a metal heat sink is configured with different dimension anodized aluminum alloy housing tube, only after leaving enough time and space for tube cooling down, this laser line generator enables long lasting green line projection within 8 to 10 hours per day. According to the use of a qualified glass coated lens and glass window inside laser tube, this 532nm green line laser module enables wide fan angles of 10 to 110 degree. In those of quite harsh working occasion of mechanical moving or shocking etc, it always gets stable performance and highly clear green reference line projection under special occasion of moisture or dust etc. When it projects high linear quality and highly straight green line within 0.5 meter to 6 meters, only after correct use of output power and optic lens degree, it just makes sure of no mistake line alignment for both industrial and high tech fields. Being made with special part of APC, ACC driving circuit board, available with wide range output power of 5mW to 100mW, this green line laser module is keeping work with constant output power and electric current supply. It maintains the most stable performance within 8 to 10 hours, and long serving lifetime of more than 8000 hours. When users are selecting high power green line laser for long distance and high lighting use, only after high attention to laser safety issue and correct wearing of laser safety glasses, it achieves highly secured and fine line generation for all application fields perfectly.
