Laser Interferometers -PTSC
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.
Verifire™
Reliable and cost effective shop floor fizeau interferometer with unmatched 3-year laser warranty.
Verifire™ HD
Higher resolution imaging exposes mid-spatial frequency features.
Dynafiz®
Highest level of performance. Reliable metrology even in extreme vibration and air turbulence.
Verifire™ XL
Measures flat surfaces up to 300 mm (12 in.) diameter without stitching. Simple part loading and alignment
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
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 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 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.
