Small volume, small power consumption, air-cooled cooling method, small footprint, easy installation, really achieve energy saving and portability. Electro-optic conversion efficiency is high, easy to use, no optical adjustment or maintenance, compact structure, high system integration, less failure. Without any maintenance, long service life, suitable for harsh environment work. Fast processing speed is the traditional marking machine 2-3 times, optical scanning galvanometer, laser repetition frequency is high, high speed without distortion.
