It is no challenge job for users to get quite precise dot alignment with the assistance of red laser diode module. When it is connected with external DC input power supply, it generates a highly bright and compact size red laser dot in targeting surfaces immediately. this is also an adjustable focus laser dot alignment tool, only after very simple screw of laser beam aperture, red laser beam is focused so as to bring uses the best dot alignment result conveniently. Red laser diode module
is very similar with red laser pointer, however, this is getting continuous red laser dot projection on targeting surfaces, thus widely used for accurate dot positioning for industrial dot alignment works including laser marking, drilling work, laser engraving machine etc. users can install this dot laser alignment tool in any device, getting easy and no mistake dot measurement for all laser used fields.
