The Verifire from Zygo Corporation is a Fizeau Interferometer with a patented QPSI acquisition and has a 160 Hz camera that provides a resolution of 1200 x 1200 pixels. It has a wired and wireless remote-controlled encoded focus switchable polarization kit with 1 - 5x optical magnification. This interferometer has a 633 nm high power stabilized HeNe laser source that produces a minimum of 3 mW class-IIIa polarized output. It has a test beam diameter of 4 or 6 inches and an optical center line of 4.25 inches. This interferometer requires an acquisition time of 81 - 188 ms with a pupil focus range of ± 2.5 m for 4 inches and ± 5.5 m for 6 inches. It can be controlled via a high-performance Dell PC, Windows 10 64-bit, Mx™ software, and has a horizontal or vertical mounting configuration.

The Verifire has 3 data acquisition modes, namely, PSI - temporal phase-shifting interferometry, QPSI – vibration robust temporal phase-shifting interferometry, and an optional DynaPhase – vibration insensitive instantaneous interferometry. It has a Quick Fringe Acquisition System (QFAS) with a twin spot reticle and requires an AC supply of 100 - 240 V. It is available in a package that measures 69 x 31 x 34 cm (for 4 inches) or 92 x 31 x 34 cm (for 6 inches) and is ideal for reflective optics, transparent optics and imaging systems.
