InterferometerInterferometer systems from ZYGO were commercially introduced over 35 years ago, and ZYGO continues to maintain leadership in surface form metrology using interferometry.
Interferometers by ZYGO were chosen over 10,000 times through the years, and many of those interferometer systems continue to be relied on daily to provide accurate production metrology of optical components and assemblies that affect our daily lives. Interferometer 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 interferometer?
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 Interferometer Applications
Verifire™ MST Interferometer - 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™ Asphere Interferometer - 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 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 Interferometer Systems - 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 interferometer systems 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.
