DynaFiz - Dynamic Laser Interferometer

Interferometry in environments with extreme air turbulence and vibration poses a serious challenge to non-dynamic, phase-shifting interferometers (PSI). Applications within such environments can push the technology past its limits as well, including setups inside vacuum or thermal chambers, those on separated metrology frames, and large optics with long optical paths. On the other hand, dynamic acquisition in turbulent air and extreme vibrations enable precise measurements to be obtained in these circumstances, permitting production-floor metrology.

The DynaFiz® dynamic interferometer by ZYGO is a ground-up new design, maximizing dynamic efficiency and performance. The DynaFiz dynamic interferometer has no patch software add-ons, as those attempting to turn an ordinary interferometer into a dynamic measurement system.

The DynaFiz dynamic interferometer captures a single frame of data and effectively freezes motion in the cavity. High quality data is now possible in the most extreme environments, while increasing speed and lateral resolution.

Dynamic Interference Measurements

The DynaFiz dynamic interferometer makes it possible to measure in numerous conditions, such as:

• Environmental chambers

• Adaptive optics

• Steering mirrors

• Air flow analysis

• Terrestrial astronomical telescopes

• Ion beam figuring

• Meter class optics and systems

• ISR systems

• Form analysis for flats, spheres, and aspheres
