DynaFiz®: Reliable Metrology in Challenging Environments

Designed for dependable interferometry in vibration-prone environments, the DynaFiz® is versatile and adaptable enough to meet various application requirements, from high-end telescope testing to live phase feedback for active optical system alignment.

The light, efficient optical layout of the DynaFiz®, coupled with the ZYGO high-power HeNe laser source, facilitates operation at high camera shutter speeds that “freeze” vibration. This dynamic capability enables reliable metrology in environments where traditional temporal phase-shifting techniques would fail.

Key Features

  • A coherent optical design allows maximum light efficiency while enhancing dynamic performance.
