Are you in need of highly stable and clear enough dot measurement? No matter it is pointing at long distance or long time use, it is always making an easy job after the use of a 445nm blue dot laser diode module. It emits intense blue laser light directly from 445nm blue laser diode. In order to make sure of highly stable and reliable dot measurement, this industrial stabilized 445nm blue laser achieves strong industrial stabilization, and highly clear and accurate red dot projection onto all raw material surfaces effectively.
