Abstract

We provide an overview of the method of confocal mirror design and report advances with respect to pupil imagery. Two real ray-based conditions, Y+ = - Y- and ΔY = 0, for the absence of linear astigmatism and field tilt are presented. One example illustrates the design of a system confocal of the object and image, and another illustrates the design of a system confocal of the pupils. Stop shifting formulas are provided. Three three-mirror anastigmatic systems further illustrate the method.
