In order to get the most satisfied dot alignment on multiple targeting surfaces, unless the use of any manual sticker, laser pointer or other mechanical dot measuring device, it is the most awful experience to make use of Berlinlasers green laser diode module. When it is projecting the easily absorbed and the most sensitive green laser light from 532nm green DPSS laser system, equipped with excellent thermal emitting system, this dot laser alignment tool is just obtaining superior thermal conductivity and highly stable dot projection in continuous work.
On various targeting surfaces, green laser diode module is keeping quite low beam divergence of less than 1mard. It is keeping the best round shape green dot projection with the most compact dot diameter. After quite easy adjustment of laser beam focus and dot targeting direction, without the use under sunlight, it is just workable with the clearest dot projection on any industrial and high tech surfaces effectively.
