Abstract

This entry begins by presenting the very basic rules of paraxial optics. A step-by-step method to solve problems by using paraxial ray tracing is explained. “Easy” rays and auxiliary rays are presented and traced, and some examples are explained with details for those readers approaching the topic for the first time. The paraxial ray tracing will find one of its practical uses in the calculation of apertures and fields.
