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.
- 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.
Products for Aspheric Optics
AccuFiz 6 MPx
The high resolution 6 megapixel AccuFiz Fizeau interferometer can measure steeper slopes, making it your best suited option for working with aspheres.
4D PhaseCam Twyman-Green interferometers are the industry choice for measuring concave spherical optics, from several millimeters to tens of meters in diameter.
