Laser Interferometers

Verifire™ Reliable and cost effective shop floor fizeau interferometer with unmatched 3-year laser warranty.

Verifire™ HD Higher resolution imaging exposes mid-spatial frequency features.

Dynafiz® Highest level of performance. Reliable metrology even in extreme vibration and air turbulence.

Verifire™ HDX Designed and built for mid-spatial frequency characterization of optical components and systems.

Interferometer Accessories - ZYGO qualifies all of our optical metrology accessories to ensure optimal interferometer performance. Our accessories include transmission and reference optics, opto-mechanical mounts and fixtures, radius of curvature hardware and vertical mounting options.

Special Applications

Verifire™ MST - The Verifire™ MST utilizes a wavelength shifting laser and patented data acquisition methods to enable simultaneous measurement of the front and back surface of transparent optics, thickness variation (including wedge) and simple 2-step homogeneity metrology without difficult part preparation or messy coatings.

Verifire™ XL - The Verifire™ XL interferometer system is a stand-alone workstation designed for simplistic and reliable metrology of large flat surfaces up to 300 mm (12 inches) in diameter, without stitching. Designed for ease of use, with a heavy duty tip/tilt stage that provides repeatable part placement without the need for custom fixturing.

Large Aperture Interferometer Systems - Large Aperture Fizeau Interferometers are available for static and phase measuring applications with 12", 18", 24" and 32" apertures (300 mm to 800 mm). ZYGO's large aperture beam expanders are an optional extension to interferometers. Taking advantage of ZYGO's powerful lasers, the beam expanders are configured to provide both a standard 4" measurement beam and a large aperture metrology source.

UV and IR Interferometers - Interferometers using invisible light at both longer and shorter wavelengths. ZYGO is expert at interferometry at a range of wavelengths, from 266 nm to 10.6 µm infrared.

Upgrade Your ZYGO Interferometer - ZYGO interferometers are built to last. Through our decades of support, as technology has advanced, ZYGO continues to offer upgrades to existing systems to improve and expand their capabilities.

'Special' interferometers - For metrology needs outside the mainstream production offerings of ZYGO - and ZYGO's catalog of standard interferometers is larger than any - we have a special group of experts dedicated to producing precision systems for limited production. Unusual configurations, wavelengths and apertures are all part of our capabilities.
