Zygo's Verifire series of laser Fizeau interferometers represent a complete line of high performance metrology instruments for the measurement of plano, spherical and aspherical surfaces and material characteristics. The systems provide a variety of proprietary acquisition techniques to ensure optimum metrology in a wide range of environments.
Verifire QPZ - high speed digital camera, accurate phase acquisition includes acquisition capability for accurate metrology in the presence of large production vibrations. 1024 x1024 pixel camera at 100Hz.
Verifire MST - wavelength shifting laser for simultaneous measurement of the front and back surface of transparent optics, thickness variation, wedge and 2-step homogeneity.The Verifire MST can measure two-, three- and even four-surface cavities. Show all of the surfaces, or only the surfaces of interest, within the MetroPro software. Artifacts are naturally suppressed using FTPSI, eliminating the need for an extended source.
The Verifire Asphere is based on two of Zygo's core competencies, the patented multi-zoned metrology method provides a high resolution aspheric surface measurement. With multiple axes of motorized stages, the Verifire Asphere offers automated alignment, acquisition and analysis of aspheres. The result is a fast, high resolution quantitative aspheric surface measurement.
The Zygo Mini interferometer is a compact self-contained metrology system, designed to meet the unique requirements of production metrology. This advanced compact Fizeau interferometer features a proprietary method of phase-shifting acquisition that enables reliable metrology in production environments.
