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.

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.

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.

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