Verifire™

Metrology workhorse of the optics shop

Verifire Laser Interferometer System
Lorem Ipsum is simply dummy text of the printing.

The Verifire™ interferometer system provides fast and reliable measurements of surface form error, and transmitted wavefront of optical components, systems and assemblies.

A true laser Fizeau design, the Verifire™ system expands upon ZYGO's unmatched experience in surface form metrology. The ZYGO-manufactured HeNe laser source  combined with ZYGO's patented acquisition algorithms and full-featured Mx™ metrology software, enables high-precision metrology with easy to use analysis capabilities

Confident Metrology on the Shop Floor

Technology for optical metrology has advanced significantly in recent years.  In the past, environmental effects needed to be carefully controlled to achieve reliable measurements.  Today, ZYGO offers technologies that enable reliable measurements in harsh environments where vibration and air turbulence can make traditional optical metrology difficult or impossible.
