Laser Interferometers

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.

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

Large Aperture Interferometer System 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.

Large Aperture Interferometer System Verifire™ Asphere - The first metrology tool for fast, non-contact, high-accuracy 3D metrology of aspheric surfaces. Production-friendly features include automated alignment, acquisition, and analysis. Based on two of ZYGO's core competencies, the patented multi-zoned metrology method provides a high resolution aspheric surface measurement.

Large Aperture Interferometer System 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.

Verifire™ 3.39 µm Interferometer System 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.
