Laser InterferometersLaser interferometers from ZYGO were first introduced commercially 45 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.
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.
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.
