AccuFiz D Interferometer
Photonics Showcase
May 2022A dynamic, on-axis Fizeau
interferometer for measuring
optical-quality surfaces.
Surface-separation technology
lets you test plane parallel
flats, concentric domes,
spheres, or isolate surfaces
in optical systems. Short
coherence distinguishes
surfaces as close as 200 μm.
Beam expanders up to 600 mm, 636 nm (visible), or 1053 nm (IR) for
measuring at operating wavelength.
