Precision 355nm F-Theta Lens for PCB Drilling & Micromachining – SL-355-400-580-D15

The SL-355-400-580-D15 is a high-performance F-theta scan lens specifically optimized for 355nm ultraviolet lasers. With a generous 400x400mm scan field and a long 580mm effective focal length (EFL), this lens provides a wide working distance (652.31mm) without sacrificing spot quality. The large aperture and 15mm input beam ensure excellent energy transmission, making it the ideal scanning solution for large-format UV laser processing, including marking, engraving, and cutting.
