    • A mirror system has four mirrors with a common optical axis, i.e. a first collecting mirror (1), a second smaller dispersing mirror (2), a third collecting mirror (3) and a fourth collecting mirror (4), seen in the direction of light incidence. Mirror (1) reflects incident light on mirror (2) that forms an intermediate image (5) of the light. The dispersed light then reaches mirror (3) that acts as a collimator and reflects parallel light on mirror (4), that in turn reflects the light on image field (6) in which a detector (7) is arranged. Mirror (1) has a central bore (10). Flat mirrors (8) fold the path of the light and are preferably arranged in the plane of intermediate image (5). An image field flattening lens (9) can flatten image field (6). Both classical Cassegrain systems and Ritchey-Chretien systems that consist of mirrors (1) and (2) may be aplanatically and anastigmatically corrected with a flat image field (6) by means of the disclosed two-mirror corrector made of mirrors (3) and (4).

    • A coude gimbal structure (30) includes a two-axis gimbal system (36) having an outer gimbal (38) pivotable about a first rotational axis (40), and an inner gimbal (42) supported on the outer gimbal (38) and pivotable about a second rotational axis (44) which intersects the first rotational axis (40) at an intersection point (46). A reflective coude optical system has a positive-optical-power primary mirror (58) mounted to the inner gimbal. The primary mirror is directed along a third axis passing through the intersection point and lying perpendicular to both the first and second rotational axes. In one aspect of the invention a coude path length of the reflective coude optical system is about half of the aperture diameter of the primary mirror. In another aspect the structure has an intersection flat fold mirror at the intersection point.
