In order to get easy and accurate dot alignment result in distance, it is just not realistic for users to still make simple use of a sticker, laser pointer or your own finger. When the real dot aligning distance of out of hand reaching distance, it is just a good job to make sure of this green laser module. Even though you are only choosing a quite low power 5mW green laser device, it is able to be seen at quite long distance, usually the green laser beam can be observed at several miles far away, thus such kind of low power green laser alignment is able to get ideal dot aligning result at quite long work distance inner room or close distance etc.
Once 532nm green dot laser alignment gets the use of high power 532nm green DPSS laser part, it is just getting quite long distance dot measuring work, while still keeping its bright and visible enough laser dot targeting in distance. Users should just be cautious enough with powerful green laser radiation and getting proper eye protection with a pair of laser safety glasses. When green laser beam is pointed at quite long distance, it is producing powerful green laser beam in use, which has just made high power green laser module workable with bright enough dot positioning result as expected.
On basis of super low laser beam divergence of no more than 1 mard, green dot laser alignment is always getting quite small size dot diameter in use. Users should always be efficient enough to make correct choice of output power and proper adjustment of laser beam focus, getting the easiest and quick laser dot instruction all the time. When this green laser diode module gets the allowing work distance of maximum 25 meters, with the easy installation and adjustment of laser beam focus and alignment laser dot targeting direction, it is just getting good dot positioning for laser marking, laser engraving, drilling and other button positioning work etc.
