Phase shifting Fizeau interferometer with ring light source

Verifire ATZ from Zygo

Verifire ATZ - highest performance interferometer with mechanical phase acquisition with a 1000 x 1000 pixel CCD camera. Ring of Fire illumination system, encoded zoom and focus capabilities.

Features
Fizeau interferometer with patentedRing of Fire artifact suppression
Standard 4" or 6" aperture
Complete accessory
Zygo transmission spheres and flats
Radius scale and downwardlooking configuration

The Verifire ATZ provides the highest level of commercial performance available in a phase-shifting interferometer. Combining unique illumination, revolutionary data acquisition, and a finely tuned electro-optical imaging system, the Verifire provides you with the technical leadership you expect from Zygo.

The patented Ring of Fire illumination system is the basis of the Verifire's clean interferometer image. The Ring of fire is a partial coherence illuminator that localizes the interference to the optical cavity. Therefore, artifacts formed by dust outside the interferometric cavity are suppressed, enhancing the Verifire's performance.
