Introduction to Mid-Spatial Frequency (MSF) Errors for Optical Surfaces

14 April 2021

Eastern Time (US & Canada) (UTC - 05:00)

Mid-spatial frequency (MSF) errors can be a source of small angle scatter or blur in an optical system. This webinar will provide an introduction to MSF errors. It will cover many questions optical designers often ask of optical fabricators, for example: What causes MSF errors on the surface of optics? How can I specify MSF errors so that my surfaces are smooth? How are you going to measure MSF errors?
