In process of the highest level of accuracy and fineness line alignment at quite long work distance, it is far more enough to reach with formal line drawing device, but substituting by Berlinlasers 445nm blue laser line generator. It generates intense blue laser light directly from a 445nm blue laser diode within 50mW to 100mW.
After easy use of 5V, 9V 1000mA DC power supply, within the maximum installed distance of 3 meters, this blue laser line generator always makes easy reaching blue laser beam and blue line alignment in distance. It allows freely adjusted blue line fineness and line emitting direction, within freely installed distance of 3 meters, it makes easy reaching, high fineness and low cost line alignment for both industrial and high tech work fields perfectly.
