LM8330-3D-1200-GST RF-Excited CO2 3D Dynamic Focus Galvo Scanner (10.6 μm, 300×300 to 1200×1200 mm Large Field, Water-Cooled, XY2-100)

Presentation of the equipment's characteristics

The LM8330-3D-1200-GST is a large-format 3D dynamic focus scanning system designed for RF-excited CO2 lasers (10,600 nm / 10.6 μm). It delivers stable operation, high positioning accuracy, fast marking performance, and strong anti-interference capability—ideal for wide-area processing and complex 3D surfaces.

During dynamic marking, the system provides high line accuracy, uniform power distribution, and distortion-free graphics, helping maintain consistent output quality across the entire working field. It is well-suited for large-format marking, engraving, cutting, and deep engraving on non-metal materials in industrial production.
