Whatever kind of working surface users are trying to make highly clear dot alignment, it is far more enough to reach with a simple blue laser pointer, it makes even better job with a Berlinlasers 445nm blue laser diode module within 50mW to 100mW. The genuine dot alignment is working for quite long time. Only after its proper use of metal heat sink and APC, ACC driving circuit board, it assures the most reliable red dot projection and long lasting use perfectly.
Being made with qualified glass coated lens and import blue laser diode inside 16mm diameter metal housing tube, this blue dot laser alignment keeps work with easy installation, quick reaching and no barrier dot alignment in distance. After its freely adjusted laser beam focus and dot emitting direction within three dimensions, it assures the most precise and the lowest price dot alignment for industrial dot alignment, laser show, laser displaying, decoration, laser communication and high tech etc.
