The new generation of portable laser marking machine developed by SINOPER, and the laser source is connected to the galvanometer scanner through a metal mechanical 7 joints articulated arm, which can be twisted and rotated to the surface of the object to perform marking and marking within a range of 360��. Because our company has the independent research and development capabilities of galvanometer scanners, we designed lightweight galvanometer scanners for YAG 1064nm laser and CO2 10.6um laser for this portable laser marking machine. The weight is only 280g, which allows operators to operate it very easy with only one hand.
