Fig. 6 — ZEMAX NSC mode results for light propagation and stop check along the z-axis ( = optical axis) in the illumination path at a wavelength of 560 nm. The plots show the distribution of light in the xy-plane in position space. (a) Source ring representing the initial annular size and shape. (b) Hole mirror plane tilted by 45°. The intermediate image at the hole mirror shows the expected elliptical shape, with a distribution in x stretched by a factor of 1.414 with respect to y. Its eccentricity at the hole mirror in x is caused by the different ray heights hitting the tilted plane. (c) Pupil ring as aerial image, 0.435 times the source ring size.
