| 发明名称 | Camera with pivotable prism | ||
| 摘要 | A camera (1), in particular in a space vehicle, having a housing (2) which contains at least one optically sensitive exposure surface (7), and a base lens (9), having a first fixed focal length, connected thereto in each case, and which projects on the at least one exposure surface (7) and which is situated on a first optical axis (10) for the exposure surface (7). To provide the camera with various fields of view, in particular for the approach of two satellites toward one another over large distances, at least two afocal supplementary lenses (11, 12) which are each parallel with respect to their optical axes (15, 16) and spaced at a distance from the first optical axis (10) are situated in the housing (2), whose optical paths are alternately coupleable with the aid of a pivotable prism (17), to form further fixed focal lengths in an optical path of the base lens (9). | ||

| 主权项 | 1. A camera comprising: a housing containing at least one optically sensitive exposure surface; a base lens having a first fixed focal length, connected thereto in each case, the base lens projecting on the at least one exposure surface situated on a first optical axis for the exposure surface; at least two afocal supplementary lenses, each parallel with respect to their optical axes and spaced at a distance from the first optical axis, and being situated in the housing; and a pivotable prism capable of alternately optically coupling optical paths of the at least two afocal supplementary lenses to form further fixed focal lengths in an optical path of the base lens. | ||
