Dynamic metrologyDynaFiz from Zygo
The new 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.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
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.
The low-noise, high resolution camera and optical magnification in the DynaFiz dynamic interferometer enables clear visualization of the mid-spatial frequency characteristics in the surface of a test artifact.
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.
