장파장 적외선용 F-Theta 스캔 렌즈

Speed up CO₂ laser-based materials processing tasks with F-theta scan lenses that enable rapid processing over a large scan field.

These scan lenses deliver small focused spot sizes with minimum distortion over large fields-of-view, thus enabling high-speed operation in marking, engraving, welding, rapid prototyping, PCB via drilling, and converting applications.
