1. An optical arrangement for a radiation detector (4) containing at least one radiation receiving region with which there is operatively correlated a first optically effective surface (3; 8; 10) containing different primary radii of curvature planes (1, 6) differ from one another, characterized by the features that, each of the radiation receiving regions (26, 27, 28) has operatively associated therewith a second optically effective surface (2; 7; 31/32; 41/42/43) containing different primary radii of curvature in the same mutually perpendicular primary curvature planes (1, 6), wherein the focal lengths (f1 , f2 ) of the optical arrangement are different in both primary curvature planes (1, 6) however the focal points in both primary curvature planes (1, 6) simultaneously coinciding at least approximately at the site of the radiation detector (4), so that in both primary radiation planes there occurs anamorphotic imaging. |
