12.7mm Diameter /10 ZERODUR Optical Flat by TECHSPEC

TECHSPEC Single Surface Optical Flats serve as a reference plate to assess the flatness of unknown surfaces. Each piece undergoes meticulous polishing by our master opticians and rigorous testing on a Zygo interferometer to ensure surface flatness. The secondary surfaces are pitch polished to window quality for clear viewing of interference patterns. These optical flats come in a robust storage case for enduring protection. Notably, λ/20 flats measuring 76.2mm or larger include a certificate of calibration.

• Diameter Range: ½” to 14”
• Certification Included: Each λ/20 Flat 76.2mm and Larger
