Zygo dynamic high resolution Fizeau interferometer

DynaFiz from Zygo

Zygo's DynaFiz interferometer provides dynamic and high-resolution accurate measurements of flat or spherical surfaces, and transmitted wavefront of optical systems and assemblies. Available in 4” and 6” versions, the DynaFiz performes accurate metrology of optics in the presence of air turbulence and extreme vibrations

Features
  • Dynamic acquisition in turbulent air and extreme vibrations
  • Capture live data
  • LivePhase enables real-time Zernike analysis
  • Movie mode captures wavefront changes over time
  • High-power, long-life, frequency-stabilized HeNe laser
  • QPSI vibration-tolerant acquisition

Further information

Its highly optimized internal optical design is made to bring high lateral resolution using 4 different acquisition technics:

  • DynaPhase  = LivePhase calibrated carrier fringes with real-time Zernike analysis)
  • 3D Movie-Mode  = continuous DynaPhase to capture wavefront over the time
  • traditional PSI = phase shifting interferometry with 13 buckets
  • fast QPSI  = shuttered PSI vibration-tolerant interferometry with 30 buckets

Like any Zygo interferometer, DynaFiz can characterize glass or plastic optical components - like flats, lenses, and prisms - and even precision machined metal and ceramic surfaces.

Optical system testing can also benefit from the unique capabilities of the DynaFiz interferometer and its ability to capture live data. LivePhase acquisition provides real-time Zernike feedback for active monitoring of the alignment of an optical system. This capability is the basis for movie mode which combines numerous dynamic images into a movie clip that provides a history of how an optic or system changes over time. Get the most from your metrology investment with the unique capabilities and unmatched versatility of the DynaFiz interferometer.
