Laser Interferometers

ZYGO laser interferometers support and enable the most demanding metrology applications in industries from semiconductor and lithography to space-borne imaging systems, cutting-edge consumer electronics, defense-related IR and thermal imaging systems and ophthalmics.

There are a number of factors to consider when selecting an interferometer – primarily what it will be used to measure and the environment in which it will operate.  ZYGO offers a range interferometers, from cost-effective production level to instruments optimized for difficult environments, and the highest resolution commercial interferometer purpose built for mid-spatial frequency characterization.  See the latest instruments, technology, and capabilities below, as well as the applications and industries we serve.

Verifire Laser Interferometer Measuring a Spherical Optic

Verifire™

339 ir verifire Interferometer face

IR Interferometers

Testing at design wavelength is critical for alignment and final qualification. ZYGO offers a range of interferometers for testing optical systems and materials at their operating wavelength, from NIR to SWIR, MWIR and LWIR – including optical references and accessories.

Verifire™ XL Interferometer System

Verifire™ XL

Large aperture, small footprint – the Verifire™ XL is a dedicated, downward-looking 12” aperture workstation for plano testing of large format optics including precision windows, mirrors, blocked optics, and wafers.

Verifire Asphere+ 700*394

Verifire™ Asphere+

The Verifire™ Asphere+ (VFA+) leverages the benefits of Fizeau interferometry to provide a unique combination of precise, high resolution, fast, and full aperture metrology for axisymmetric aspheres.

verifire multiple surface test

Verifire™ MST

The Verifire™ MST (Multiple Surface Test) interferometer allows simultaneous measurement of multiple parallel surfaces. Extract individual surfaces from a complex fringe pattern and easily qualify surface shape, inhomogeneity, thickness variation (TTV) and more.

Computer generated hologram

Computer Generated Hologram

A CGH (Computer Generated Hologram) is an optical null element that creates a unique wavefront enabling interferometric testing of complex optical surfaces including freeform, gullwing and off-axis aspheric shapes.
