With the assistance of advanced 532nm green DPSS laser tech and qualified glass coated lens with different fan angles, it is developing into the most practically used device of 532nm green line laser module. It is performing much better than any formal manual or mechanical line aligning tool. According to correct use of glass coated lens degree and output power, after proper installation and adjustment of laser beam focus, this green laser line generator is just able to work with highly clear and straight green reference line projection onto various working surfaces effectively.

According to the use of an external AC/DC adapter, within wide range output power of 5mW to 100mW, green line laser module is able to work with highly clear and intense green laser beam emission from beam aperture. According to real thermal consumption, it is just adopting different size tube diameter of 16mm and 26mm. In addition, after correct use of 5V, 9V 1000mA DC power supply, this green laser line generator is leaving enough space for inner tube cooling down, but also making sure of continuous green laser beam and green reference line projection from beam aperture constantly.
