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 ZygoŽ 33mm although at a different f/#.
- Substrate material: Fused Silica
- Surface figure: λ10 at 633nm
- 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
- Wedge surface R ≤0.25% at 633nm
