F-Theta Scan lens F254-W1064

F-Theta scan lens is widely used in micro material processing, such as drilling, dicing, fine cutting, structuring, perforating, marking and welding. Our F- theta lens can achieve large flat field image with high performance. The diffraction limited performance of the scan lenses results in minimum spot sizes with high uniformity over the whole scan field.…
