ZYGO's 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 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.
