Interferometer Flats
CVI
Serie IF Wedge 30 ±5 minutes
- Substrate material: Suprasil 1, UV grade fused silica or BK7
- Wedge tolerance: 30 ±5 minutes
Transmission Spheres
CVI
Serie TSC Transmission spheres are used to measure convex or concav spherical surfaces.They are designed to fit most commercially available interferometers, including the Zygo® 33mm although at a different f/#.

- 2" and 4" clear apertures standard
- Compatible with standard bayonet-style GPI mounts
Transmission and Reference Flats
CVI
TF & RF series Transmission flats are mounted on interferometers to measure flat substrates.
- Material: Fused Silica - Transmission flat
- Material: zeroduc glass - reference flat
- Surface figure: λ20 at 633nm - reference surface
- Anti-reflection coated: transmission flat-reference surface uncoated
