Click to learn more about ZYGO's complete selection of interferometer accessories.

Since the introduction of our first commercial interferometer over 35 years ago ZYGO continues to maintain the leadership role in surface form metrology. Thousands of ZYGO interferometers are installed worldwide and relied upon daily to provide accurate production metrology of optical components and assemblies that affect our daily lives. Applications span across a wide range of applications in numerous industries including consumer electronics, ophthalmic, semiconductor and defense & aerospace. ZYGO is the one optical metrology company that is trusted across the globe to qualify the worlds most critical optics. Shouldn't you be using a ZYGO?

VeriFire™ Series - The ideal choice for accurate metrology of surface form for quality control, R & D, 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 Systems - ZYGO's large aperture beam expanders are an optional extension to the VeriFire™ and GPI™ Series of interferometer mainframes. The beam expanders are configured to provide both a standard 4" measurement beam and a large aperture metrology source. Large Aperture Systems are available for static and phase measuring applications with 12", 18" 24" and 32" apertures.

GPI™ Series - The GPI™ series of interferometers include production metrology solutions that offer qualitative visual fringe metrology and dynamic acquisition for applications with in environments with extreme vibrations.

PTI™ 250 Series - A compact series of interferometers operating at a wavelength of 650 nm with aperture options of 6 mm, 25 mm and 50 mm. The PTI™ 250 interferometer is the ideal solution for production metrology of small optics and assemblies.

DVD400™ Series - The DVD400™ series of interferometers provides high-accuracy transmitted wavefront metrology of DVD optical components at an operational wavelength of 405 nm.

Expanded Wavelength Capabilities - ZYGO's precise phase-shifting interferometer solutions are available in several additional wavelengths ranging from 248 nm to 10.6 µm.

Accessories - ZYGO qualifies all of our 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.

Upgrades - ZYGO interferometers are built to last. As technology advances ZYGO offers the ability to upgrade existing systems to current state-of-the art capabilities.
