Verifire™ Interferometer System

The Verifire interferometer system offers quick and accurate measurements of the transmitted wavefront and surface form error of optical parts, systems, and assemblies.

The Verifire system, an actual laser Fizeau design, builds on ZYGO’s unrivaled knowledge in surface form metrology. The HeNe laser source created by ZYGO, paired with ZYGO’s unique acquisition algorithms and full-featured Mx metrology software, allows high-precision metrology with simple analytical capabilities.

Confident Metrology on the Shop Floor

In recent years, optical metrology technology has made great strides. In the past, carefully managing environmental factors to get accurate readings was necessary. Modern methods from ZYGO provide precise measurements in challenging conditions where air turbulence and vibration can make standard optical metrology difficult or impossible.

More Info

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

Standard features include the unequaled three-year guarantee on the ZYGO-made HeNe laser source, full-featured Mx software for powerful yet user-friendly measurement, analysis, and automation, and QPSI vibration robust acquisition.
