What it is

The Zygo GPI to Verifire is a precision optics instrument, specifically a laser Fizeau interferometer, designed for optical metrology.[1]

How it works

The instrument uses a laser light source, and the beam expander conditions the beam aperture to match the part under test.[2][3]

The Verifire platform adds modern imaging and vibration-tolerant measurement technology to the optical metrology capability.[1]

Where it fits in the process flow

General reference — not yet source-verified

Precision optics interferometers are used in manufacturing and quality control to verify surface form, flatness, and transmitted wavefront error of optical components.

Such instruments are typically employed in metrology labs and production inspection steps, after polishing or coating, to qualify optical elements before assembly.

Applications

General reference — not yet source-verified

Typical uses include measuring flatness, parallelism, and surface quality of optical flats, mirrors, and other polished components.
