The ZYGO DynaFiz™ dynamic laser interferometer is a highly optimized optical instrument designed specifically for performing accurate metrology of optics in the presence of air turbulence and extreme vibrations.

The high light efficiency of the DynaFiz™ interferometer’s optical system, combined with its long life, 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.
