If there is not quite clear dot alignment at quite longer work distance than formal hand reaching, it would be quite nice experience to make use of a high intensity beam Berlinlasers blue laser diode module. It is employing high power 445nm blue laser diode as its laser beam emitting source. Besides formal design with metal heat sink cooling system and APC, ACC driving circuit board, it is also getting the most important design part of metal housing material. This laser dot alignment tool gets superior nice thermal conductivity, and then easily obtaining highly stable dot alignment in long term use.
In order to get constant dot targeting, blue laser diode module gets support from DC input power supply. The genuine blue laser dot alignment is featured by high temperature resistance and corrosion resistance. It is able to work with highly stable blue dot targeting within daily operating time of 8 to 10 hours. Users should not only install it on correct position, but also pay special attention to powerful laser light and thermal energy, this high power blue laser dot alignment tool just obtains the most accurate dot instruction for all high tech fields marvelously.
