Description

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.
