The invention relates to a mirror system with two mirrors, comprising a concentrating reflector and a diffusing reflector fitted on the same optical axis, an image field and a detector. The diffusing reflector has a central drilling. A diaphragm is arranged in such a way that the point of intersection of the plane of the diaphragm and the optical axis forms the center of the curved image field of the mirror system. At the edge of the diffusing reflector there is a central diffuse light shutter. The concentrating reflector may optionally have a central drilling. The mirror system may be used as a telescope system. Prior art two-mirror systems like the Ritchey-Chretien system do not correct astigmatism, image field curvature and distortion. According to the invention, spherical aberration, coma, astigmatism and distortion are corrected by double reflection from the concentrating reflector and the substantially hyperbolic shaping of both mirrors.
