Understanding paraxial ray tracing

Paraxial rays and parabasal rays are often used in OpticStudio to calculate system data and analysis results. It is important to understand what these rays are in order to avoid confusion in analysis results. This article discusses these special rays and how they differ from each other and from real rays.

How to Generate Cross-Section and Moment Data for an Extended Source using Geometric Image Analysis

This article describes how to use the Geometric Image Analysis feature to generate cross-section plots of and moment data (centroid, RMS width) for an extended source. This feature may also be used to generate results for a point source (in the limit where the source size is set to zero), allowing Geometric Image Analysis to supplement results provided by the Spot Diagram.
