DynaFiz®
Confident Metrology for a Dynamic World

Purpose built for reliable interferometry in vibration-prone environments; versatile and flexible enough to address a wide range of application needs from high-end telescope testing to live phase feedback for active alignment of optical systems.
The light efficient optical design of the DynaFiz®, combined with the ZYGO high power HeNe laser source, enables operation at high camera shutter speeds that "freeze" vibration. This dynamic capability provides reliable metrology in environments that are too violent for traditional temporal phase shifting techniques.
