Not easy to reach with a simple blue laser pointer, in order to make precise enough dot indication at long work distance, it makes good job to operate a Berlinlasers 445nm blue dot laser alignment. It projects moderate brightness and highly visible blue laser beam from 445nm blue laser diode within 50mW to 100mW, thus assuring highly clear blue dot indication within long extending distance of 25 meters.

This blue laser diode module applies qualified glass coated lens. It is keeping work with stable and no decay light dot projection. After a series of beam stability and aging preventing test up to 24 hours and proper use by skilled users, it assures highly reliable blue dot projection under multiple working occasions. When it makes freely adjusted laser beam focus and dot emitting direction, not relying on any manual labor force input, it assures the lowest price and the most stable dot alignment for laser show, laser displaying, decoration, military targeting, laser communication and high tech work etc.
