ZYGO's Verifire™ HD interferometer system provides fast high-resolution measurements of flat or spherical surfaces, and transmitted wavefront measurement of optical components and assemblies. The interferometric cavity length is precisely modulated while a high-speed camera captures several fringe images, which are analyzed by the software to create a highly detailed measurement of the part being tested. The system's hi-res camera and optimized optical design reliably measures mid-spatial frequency surface features that have been difficult to discern in the past. Plus, ZYGO's Mx™ software package provides the facility to quantify mid-spatial frequency content with powerful Power Spectral Density (PSD) and diffraction simulation tool. QPSI technology eliminates ripple and phase noise caused by common sources of vibration, which means you can use the Verifire HD system right on the production floor, without the hassle and expense of vibration isolation tables.
