Profile: Zygo Corporation is a supplier of optical metrology instruments, precision optics, electro-optical design and manufacturing services. We specialize in noncontact interferometric metrology process control and R&D tools for semiconductor, optics, display technologies, precision machining, photovoltaic, and research applications. Our interferometer systems are perfect for measuring surface form on super finished surfaces up to 6 inches in diameter, or larger with aperture converters. Our industrial metrology systems can be integrated with automated part handling for exact placement, removal, and sorting. This capability greatly improves the throughput of the measurement process, frequently making it possible for 100% inspection of all manufactured parts. Our semiconductor metrology systems enable manufacturers to improve the quality and yield of their processes, while lowering metrology costs. Our laser fizeau interferometers are the industry standard for no contact measurement of surface form and transmitted wave front of optical components & assemblies. Our interferometer systems offer a range of operational features and data analysis tools unmatched in the industry.
