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™

DynaFiz®
Measure in the most extreme environments, the Dynafiz is the most capable dynamic interferometer in the industry, purpose built and backed by patented technology.

Verifire™ HD/HDX

IR Interferometers

Verifire™ XL

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™ 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
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.
