Herrig Schiefspiegler Telescope

A Herrig Schiefspiegler telescope consists of two spherical mirrors usually with large radii, but with four reflections in a double-pass configuration, which makes the telescope setup very compact. With the non-sequential ray and field tracing techniques in VirtualLab Fusion, a Herrig Schiefspiegler telescope is modeled, with the multiple passes between two mirrors fully taken into account, and the image quality is investigated with respect to different incident angles.
