Feature:
- 1. F-Theta scan lens is widely used in micro material processing , such as drilling, dicing, fine cutting, structuring, perforating, marking and welding.
- 2. Our high precision F-Theta lens can achieve large flat field image with high performance.
- 3. The diffraction-limited performance of the scan lenses results in minimum spot sizes with high uniformity over the whole scan field.
- 4. Our F-theta scan lenses are delivered with highly durable anti-reflection coated protective windows to avoid contamination of the front lenses during the process.
- 5. In conjunction with appropriate scan systems, our scan lenses allow precise imaging for highly accurate micro-machining.
