High-precision optical reference flat used for inspection and system calibration.
Key Features
1. Surface flatness: RMS: λ/45 to λ/50, ideal for precise interferometry
2. Available sizes: Φ100, Φ150, Φ200, Φ260, Φ320, Φ360, Φ420 (customizable)
3. Materials: Fused quartz, glass-ceramic, excellent thermal stability
4. Widely used in wavefront error detection, surface flatness calibration, and interferometer validation
5. Custom mounting and mechanical interface available
6. Equipped with a two-dimensional goniometer to meet the angular requirements during the calibration process.
