!%The Optical Systems Div. of Zygo Corp.%! has been awarded a $4 million order from a major medical device manufacturer to produce high-precision assemblies used in an ophthalmic medical instrument. The devices will be manufactured at its Electro-Optics Group in Tucson, Ariz., which specializes in metrology-based manufacturing and precision active assembly of optical systems for the life sciences, semiconductor and defense markets. Based in Middlefield, Conn., Zygo also is a supplier of optical metrology instruments. The Optical Systems Div. also has been awarded a $9 million contract with the College of Nanoscale Science and Engineering at the University at Albany in New York and the SEMATECH consortium of chipmakers to develop extreme-ultraviolet lithography optics that will be incorporated into the fifth-generation Micro-Exposure Tool (MET-5) at the college’s Albany NanoTech Complex. The MET-5 program, managed by the consortium, is intended to aid researchers in extending semiconductor lithography resolution capability to less than 16 nm. Development and production are expected to take place over a 22-month period.
