Once users are not clear how to get quick and accurate enough dot alignment at different work distances, it is a very nice chance for users to have a try of Berlinlasers green laser diode module. It is a very nice dot measuring tool applicable for industrial dot alignment works, including laser marking machine, textile garment button positioning work, laser engraving machine or others etc.
This green laser diode module gets low laser beam divergence of less than 1mard, thus green laser dot is available with quite small size, which is able to make super clear and quick laser dot alignment at quite long work distance and higher lighting occasion. Users can also make simple screw of laser beam focus to make green laser beam focused temporarily. Only if the real laser dot alignment is avoiding eye exposure or sunlight targeting work, a correct output power made green laser module can make high speed and no mistake dot alignment result all the time.
