Unless the time users are not able to get clear enough dot alignment at quite short time, I would miss the good chance to use Berlinlasers 445nm blue laser diode module. It is just a very special dot alignment tool, which is keeping direct laser beam emission from 445nm blue laser diode and getting nice designed metal heat sink cooling system inside its 16mm diameter tube. This high power blue laser module keeps stable dot alignment within 8 to 10 hours a day.
The real dot alignment with 445nm blue laser diode module is much easier than any other manual or mechanical dot alignment tools. It is workable without barriers caused by work distance, height, working environments etc. Users can also make easy installation of this blue laser module on any industrial device. When this blue laser alignment is generating charming and attractive laser light, it is able to make wonderful dot alignment for laser show, laser displaying, decoration and military targeting work etc.
