Zygo Corp., a worldwide supplier of optical metrology instruments and high precision optical systems, announced that its Metrology Solutions Division has received orders for $3.5 million for large aperture laser interferometer systems from several Chinese optical research and manufacturing organizations. The large aperture interferometers include systems capable of measuring up to 32 in (800 mm) diameter parts and another capable of 18 in (450 mm) diameter components, along with an upgrade of an existing Zygo 24 in (600 mm) interferometer system. These instruments will be used for the development and manufacture of very large dimensioned optical components and systems, enabling precision surface shape and glass homogeneity measurements. "These orders are especially gratifying because selection was based on exhaustive technical evaluations focused on achieving the highest level of performance possible," commented Dan Musinski, senior product manager. "In association with Zygo's joint venture in Shanghai, China, the Zygo team, led by Dr. Lifeng Yin, general manager of ZygoLamda Metrology Instrument Company Limited, was able to demonstrate Zygo's commitment to the customers' needs by offering advanced technology, as well as local service and support," said Donald Battistoni, executive director of Worldwide Sales.
