Any time users are trying to make highly clear dot alignment at great distance and other formal lighting working occasion, not the same as a simple blue laser pointer, it makes even better job with an intense beam 445nm blue laser diode module. It is getting constant power source from 5V, 9V 1000mA AC/DC adapter, available with wide range output power of 50mW to 100mW, it is projecting highly intense blue laser beam, and highly clear blue dot alignment at long work distance and other formal lighting occasion. Within freely installed distance of 3 meters, not relying on any manual labor force input, this blue dot laser makes sure of no barrier, no mistake and noncontact blue dot alignment for both industrial and high tech work fields perfectly. https://www.berlinlasers.com/445nm-blue-laser-diode-module
