What is the best job for users to make highly clear and accurate dot alignment? It is not easy to reach with a simple blue laser pointer, but making even better job with a direct diode made Berlinlasers 445nm blue laser diode module. It is projecting intense blue laser light directly from a 445nm blue laser diode up to 50mW to 100mW.
Being made with a qualified glass coated lens and up to 24 hours aging preventing and beam stability test, this 445nm blue laser diode module is projecting highly clear blue laser light, and no decay light in long lasting use. According to correct use of output power and freely adjusted dot diameter, this blue dot laser gets concentrated blue laser light and increasing accuracy dot generation at great distance perfectly.
