Abstract

It is shown that supplementing an afocal aberration-free Mersenne system with interchangeable mirror objectives and mirror–lens objectives makes it possible to obtain a number of optical systems for a compact objective of a high-aperture telescope that form an image that possesses aplanatic, anastigmatic, and plananastigmatic correction of aberrations with the required relative aperture. The length of the system in this case is about a factor of four less than the diameter of its entrance pupil.
