Increasing accuracy device of a 532nm green line laser module
In those of industrial and high Tech precise line positioning work fields, although it is pointing at close or long distance, it should be a very nice chance for users to operate a highly bright beam emitting tools, such as a 532nm green line laser module. It is always projecting the most visible and the brightest green laser light source from a middle wavelength 532nm green DPSS laser system....
