Interferometric Radius Measurements
Kate Medicus, Optimax Systems
Abstract Spherical optical components are typically specified by the surface’s radius. For highest accuracy, the radius is measured using a phase shifting interferometer. In this talk, I will introduce the interferometric radius measurement and discuss how this measurement is typically done in industry. I will review some of the common sources of uncertainty in the radius measurement and show how these uncertainties can be reduced. These uncertainties include positioning accuracy, environmental effects, stage error motions, and model assumption inaccuracies.
Pre-meeting dinner will be held at Delmonico’s Steak House (125 White Spruce Boulevard, Rochester) at 5 p.m. For reservations please contact Yuhong, firstname.lastname@example.org or call 585-354-5572 by Monday, February 20th.
Biography Kate Medicus, Ph.D. is an Optical Engineer and Metrologist at Optimax Systems. She obtained her BS in Mechanical Engineering at Virginia Tech, and her MS and Ph.D. at UNC Charlotte.
Kate comes with a strong metrology background through work at NIST and her Ph.D. work from the Center for Precision Metrology at UNC Charlotte. Within the study of precision engineering, she focused on metrology and more specifically on the interferometric measurement of optical surfaces.
Kate most recently worked for a Mitutoyo RCE in The Netherlands developing metrology tools and has over 10 years in research experience. Kate recently joined the Optimax R&D team as the resident metrology expert. She has the expertise to discern between good and bad interferometric measurements and can help achieve highly accurate and reliable results.
