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