Fizeau Continuous Zoom Interferometer

A Fizeau Interferometer that has continuous OPTICAL zoom breakthrough. They said it couldn’t be done, but here’s a quick demonstration of the 4D Technology Accufiz with zoom option.

Benefits:

• use one interferometer for different sizes of optics
• get more spatial resolution
• examine detail better
• use full pixel array to get higher slope tolerance

This unique Fizeau uses optical (and optional digital zoom). Measured performance shows no imaging degradation from 1x to 3x.

Measure more optics, see better. See with 4D.
