Constant Dot Aligned Berlinlasers 488nm 5mW to 100mW Blue Laser Diode Modules
If users are trying to make highly clear dot alignment at different work distances, a 5V, 9V 1000mA DC power supply made 488nm blue laser diode module just makes sure of highly visible blue laser beam emission, and high speed blue laser dot projection at various work distance. After correct use of output power and proper mounting onto industrial machine or device, blue dot laser brings users no track and no mistake use in all application fields.
