graduated from MIT in optical instrumentation, has an M.S. from FIT, and over 40 years of experience in optical system and coating development and production. He is very experienced in practical thin films design, process development, and the application of industrial Design of Experiments methodology. He is the inventor of a robust plasma/ion source for optical coating applications. He worked in optical instrument development and production at Perkin-Elmer and Block Associates. He developed automatic lens design programs at United Aircraft Research Laboratories. He formed Willey Corporation in 1964 and served a wide variety of clients with consulting, development, prototypes, and production. In 1981 he joined Martin Marietta Aerospace and was Director of the Optical Component Center where he was responsible for optical fabrication, coating, and assembly. He joined Opto Mechanik in 1985 where he was responsible for the development of all new technologies, new instruments, and production engineering. He was a Staff Scientist at Hughes Danbury Optical Systems. He holds four patents and has published many papers on optical coating design and production, optical design, and economics of optical tolerances. He has published books on optical thin film coating design and production since 1996. His recent books are “Practical Design of Optical Thin Films”, 4th Ed. (2014) and “Practical Production of Optical Thin Films,” 2nd Ed. (2012) He is a fellow of the Optical Society of America and SPIE and a past Director of the Society of Vacuum Coaters. He now is a consultant in the above-listed technical and forensic areas. Here he is concentrating on teaching optical thin film design and production, and also aiding clients in process development and improvement.
