If there is quite strict requirement of dot aligning accuracy, users should not give up Berlinlasers blue laser diode module. it is keeping direct blue laser beam and blue dot targeting from its 445nm blue laser diode. Equipped with import laser diode tech, this blue laser module is just effective enough to get at least 40% improvement of laser beam stability. Users can make quite easy installation of this dot laser on desired working surface, and then getting easy dot instruction for special fields, including decoration, military targeting, laser show and laser displaying work etc.

This blue laser diode module is using very compact design, available with aluminum alloy housing and metal heat sink cooling system, it is able to work with constant blue reference dot targeting from laser beam aperture part. In addition, according to quite easy screw of laser beam aperture part, high intensity and high power laser light is temporarily focused, and then forming into the clearest blue dot in distance. Users can install this laser dot alignment tool on correct place, and pay special attention to powerful laser light, and then making sure of secured dot alignment effectively.
