TECHSPEC® Dual Surface Optical Flats

Dual Surface Optical Flats
  • 1/4λ, 1/10λ and 1/20λ Surface Flatness Options
  • Certified with a Zygo Interferometer
  • Each 1/20λ Flat Includes a Certificate of Calibration
  • Single Surface Optical Flats Also Available

Our dual surface optical flats are precision ground and polished to the stated accuracies on both surfaces so that either face may be used for test applications. Both surfaces are tested and certified by our Zygo Interferometer. Each flat ships in a durable storage case for permanent protection. 1/20λ flats also include a certificate of calibration.
