Laser interferometers from ZYGO were first introduced commercially over 35 years ago. Today, ZYGO continues to maintain the leadership role in surface form metrology using laser interferometry. Thousands of ZYGO interferometers are installed worldwide and relied upon daily to provide accurate production measurements of optical components and assemblies, things that affect our daily lives. Applications span across a wide range of industries, including consumer electronics, ophthalmology, semiconductor and defense & aerospace. ZYGO is the one optical metrology company that is trusted across the globe to qualify the world's most critical and precise optics. Shouldn't you be using a ZYGO laser interferometer?

Zygo Mini™ Production Laser Interferometer - A compact, self-contained, phase-shifting Fizeau interferometer system, with a streamlined touch-screen user interface. Mini interferometer meets the unique requirements of optics production metrology which is moving to precision greater than are available from visual interferometric testing.

Zygo Mini™ XP Interferometer System New! - Has all the great features of the Zygo Mini and adds built-in advanced applications, giving it flexibility to move beyond simple production line testing, making it right at home in the lab as well.

DynaFiz™ Dynamic Interferometers - highly optimized dynamic Fizeau laser interferometer for performing the most precise measurement of optics in the presence of air turbulence and extreme vibrations.

Verifire™ Fizeau Interferometer Series - the ideal interferometry choice for accurate metrology of surface form. Verifire laser interferometers are used worldwide in quality control, R&D, and production test applications. The Verifire family of interferometers are quantitative phase shifting interferometers for use in the measurement of flat, spherical and aspheric optics.

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 the Verifire™ and GPI™ series of interferometer mainframes. 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.

GPI™ Laser Interferometer Series - The GPI™ laser interferometer series includes production form metrology solutions ranging from visual fringe inspection for qualitative assessments, to dynamic-capable interferometer systems for environments which have vibrations.

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.

'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.

Interferometry 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.

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.
