The 3D laser marking machine adopts advanced pre-focusing mode, and has more dynam ic focusing seat, which adopts the principle of light, similar to the working principle of candle imaging. By means of software control and moving dynamic focusing mirror, the laser beam can be expanded to change the focal length of the laser beam before it is focused. The front-focusing optical mode used in 3D marking uses larger x-and Y-axis deflection lenses, so it can allow larger laser spot, better focusing accuracy and better energy effect; If 3D marking and 2D marking in the same focus precision work, can mark the range can be larger.
