PCT/CH91/00260 Abstract of the Disclosure A double reflector is described which comprises two spaced apart primary mirrors oriented toward a common focus. The optical system further comprises two separate secondary de- flector mirrors as well as tertiary deflector mirrors for beam concentration on a common focus. Both the primary mirrors and the secondary deflector mirrors are so-called off-axis reflec- tors, i.e. their surface represent surface sectors of a hypo- thetical big aspherical mirror body each. As surface sectors of a hypothetical big hyperbolic mirror, the primary mirrors are inclined at an angle with respect to the common optical axis and each disposed at a given spacing from the same in such manner that the inner marginal rays of the incident ra- diation which are closest to the optical axis, will converge. As of a diameter of > 8 m, the primary mirrors are to be com- posed of individual segments, each be coupled (sic, the trans- lator) with the respective associated segments of the second- ary deflector mirror, which are located opposite them in the beam path, by way of a high-precision computer assisted measuring system such that each deviation of the primary mirror segments in their bearing position is enabled by a cor- rective movement of the respective opposite segments of the secondary deflector mirror, carried out in real time by way of actuators.
