About This Webinar
Optical manufacturing has become increasingly challenging as specifications tighten for wavefronts, form, slopes, and mid-spatial frequency features. Interferometers are essential tools to control these parameters. But, like with all measurement tools, results vary between interferometers, and process control cannot be better than these variations.

With tighter tolerances and the required higher imaging resolution, even small variations cause disagreement within an operation and with downstream customers. Smythe addresses how to minimize these variations and disagreements. Attendees will be able to advance their optical manufacturing processes and improve their competitiveness. Smythe discusses topics including reference accuracy and calibration, interferometer optical design-related performance, and annual system calibration. He provides a reference to more resources that covers software analysis program-to-program variations, tolerance bands, annual calibration, and environmental variables, which all affect correlation and system performance.

About the presenter

Robert SmytheRobert Smythe began his career grinding and polishing mirrors for telescopes. Then, after obtaining a degree in astrophysics, he worked at Tropel (Corning) for five years, where he designed advanced Fizeau and Twyman-Green interferometers for semiconductor optics and industrial applications. This was followed by over 20 years of service at Zygo Corp., where he designed, developed, and marketed interferometers. During this time, he led the development of MetroPro software, NewView profilers, and the Verifier Asphere Scanning Fizeau, among other products. After a five-year period of consulting to industry leaders in interferometric metrology, Smythe co-founded Äpre Instruments to use his experience to help advance the field of interferometers, with a focus on optical manufacturing.
