Employing the best quality Powell lens (separate crystal lens), whatever kind of working surface it is pointing, green line laser module is just projecting the brightest green laser light, and highly uniform green laser line. Owing to the use of advanced 532nm green DPSS laser tech, available with the lowest laser beam divergence, it is always performing with the brightest and the most easily absorbed green laser light. Unless it is pointing under sunlight, high power green line laser also makes quite clear line alignment at long distance and high lighting as well.
