If users are not able to find a correct method to get clear enough dot alignment at quite long distance, it is just a good chance to make use of Berlinlasers green laser diode module. Owing to its good use of qualified glass coated lens, green laser beam emitting keeps high laser beam transmittance, thus green laser dot is just clearly visible at quite long distance. When the real laser dot alignment is properly controlled within 25 meters, this green laser module just gets no mistake and no light decay dot targeting for all industrial precise machinery processing works effectively.
This green laser diode module is very easy to operate, getting much more convenient use than manual dot targeting from a sticker, laser pointer or your own finger. Users can make free adjustment of laser beam focus, when green laser beam is concentrated into a quite compact size, this green laser module is just regarded as the first choice for users to get the clearest dot alignment all the time. After quite easy installation and adjustment of laser dot targeting direction, 532nm green laser alignment makes no mistake dot targeting for laser marking, laser engraving, drilling and others etc.
