Beam expansion for 6" Fizeau interferometers

6" → 8"8" beam expansion for 6" interferometers
6" – 8" Beam Expander – Beam expansion for 6" Fizeau interferometers
Highlights

Built for the production floor.

  • the XONOX 6" - 8" Beam Expander has been designed to be fully compatible with commercially available 6" Fizeau interferometers
  • the Beam Expander and matching 8" Transmission Flat in λ/20 PVr quality are ideally suited for evaluating transmitted wavefront error or surface figure error of large aperture optics
  • additional diffractive holograms or null lenses might be used to test large aperture optics of various shapes
  • optional dedicated fixture to facilitate the usage of the Beam Expander and Transmission Flat in horizontal setups. The Fixture has been designed to support the weight of the assembly without restricting motion along the optical axis
  • fine adjustment system for perfect setting to the systems optical axis
