  • λ/20 Accuracy
  • Compatible With Many Bayonet Style Housings
  • Interferogram and Certificate of Compliance Included

λ/20 Surface Accuracy Transmission Flats are designed for use with an interferometer to precisely measure an optical surface’s flatness or transmitted wavefront. These fused silica transmission flats are mounted in aluminum bayonet style mounts, making them compatible with most interferometer systems. λ/20 Surface Accuracy Transmission Flats are available in two sizes and feature an Anti-Reflection coated first surface and an uncoated second surface. These mounted precision optics include an interferogram of the surface and certificate of compliance, and are shipped in a protective storage case.
