Verifire™ Laser Interferometer

The Verifire™ interferometer system from Zygo offers rapid and trustworthy measurements of surface form error and transmitted wavefront of optical components, systems, and assemblies.

The VerifireTM system, a true laser Fizeau design, builds on ZYGO’s unrivaled experience in surface form metrology. The HeNe laser source manufactured by ZYGO, coupled with ZYGO’s patented acquisition algorithms and full-featured MxTM metrology software, enables high-precision metrology with simple analysis capabilities.

Confident Metrology on the Shop Floor

In the past few years, technology for optical metrology has advanced considerably. In the past, environmental effects were cautiously regulated to obtain trustworthy measurements.

ZYGO provides technologies that allow trustworthy measurements in harsh surroundings where air turbulence and vibration could make conventional optical metrology hard or impossible.

More Info

The Verifire™ Laser Interferometer provides flatness metrology and surface form of optical components and wavefront of optical systems and subassemblies like windows, lenses, mirrors, prisms—and even ceramic and precision machined metal surfaces.
