Enabling high-performance optical fabrication with sub-aperture finishing and stitching interferometry

Commercially available sub-aperture polishing and measurement technologies have changed the landscape of precision optics manufacturing. Such developments have enabled the production of higher precision and more complex optics with increasingly difficult figure requirements. Magnetorheological Finishing (MRF®) is a production-proven, deterministic sub-aperture finishing method that overcomes many limitations of traditional polishing. Sub-aperture Stitching Interferometers (SSI®) extend the effective aperture, dynamic range, and accuracy of phase measuring interferometers by combining novel software and hardware. QED has pioneered these finishing and metrology techniques over the past decade. Some of the latest developments on how MRF and stitching interferometry may be combined to enable cost effective manufacturing of a wide range of precision optical surfaces will be presented. Some interesting aspects of growing a business from a university spin-off to a wholly owned subsidiary of a publicly traded company will also be covered.

Don Golini

Don Golini, President and co-founder of QED Technologies International, has spent most of his career in the development, management, and commercialization of new technologies related to the manufacturing of precision optics. QED develops, manufactures and markets precision finishing and metrology equipment for the optics industry.  In July 2006, QED was acquired by Cabot Microelectronics Inc, an Illinois based company specializing in the polishing of semiconductor wafers. Prior to founding QED, Don managed the research program at the Center for Optics Manufacturing at the University of Rochester and worked on large optics manufacturing and R&D at Itek Optical Systems.

His academic background includes an MS degree in Electro-Optics from Tufts University, and a BS degree in Optical Engineering from the University of Rochester.  He has authored many technical publications, assisted in conference and technical session planning for OSA, SPIE, and ASPE, and is named on 7 US Patents.  He has served as a technical referee for Applied Optics, Optical Engineering and the US Department of Energy (DOE). He is a former President of the Rochester Chapter of the Optical Society of America, and is currently an adjunct faculty member at the University of Rochester’s Simon School of Business.
