Date: Thursday, April 14th.
Time: 6:00 - 6:35 AM PDT, and 11:00 - 11:35 AM PDT
Presenter: Paul Colbourne, Senior Optical Designer at Lumentum
In this webinar, Lumentum’s Paul Colbourne will describe how to use skew rays to model Gaussian beam propagation in OpticStudio. Skew rays are an efficient and accurate representation of Gaussian beams and can be used to quickly optimize for best focus or to minimize aberrations. Paul will demonstrate how to set up User-Defined Surfaces to generate skew rays, how to view circular Gaussian beams in 3D layout diagrams, and how to optimize systems with circular Gaussian beams. In addition, Paul will explain general astigmatism, and how to calculate the properties of a generally astigmatic Gaussian beam in OpticStudio using a ZPL macro. Paul will also show how to use a merit function macro to optimize systems with elliptical or generally astigmatic Gaussian beams.
