Abstract:
A pivoting device for pivoting a pivoting objective (O) disposed concentrically therein about two pivoting axes (Y, Z) that intersect at a right angle in an axis point of intersection (M) in the optical axis (X) of the pivoting objective, the pivoting objective (O) being held in an objective holder (OH), which is seated in bearings (L1, L2) so as to pivot in two degrees of freedom of a spherical surface, the bearings (L1, L2) being disposed on a stationary holding frame (HR), on which two pivoting-control elements (KY, KZ) are fixedly held, one of which is operatively connected to a meridian sector gear (SZ1, SZ2), while the other is operatively connected to an equatorial sector gear (SY1, SY2), of the objective holder (OH), the latter being disposed on the objective holder (OH) so as to be displaced in a meridian plane, characterized in that the meridian and equatorial sector gears (SZ1, SZ2; SY1, SY2) are guided by an anti-rotation mechanism (FK, FN), which secures them against relative rotation, on a circle, with respect to the holding frame, about the axis point of intersection (M), and the equatorial sector gear (SY1, SY2) can be pivoted in a pivot bearing (KK1, KK2) and displaceably seated in a guide (SA) on a meridian circle on the objective holder (OH) for an ecliptic pivoting compensation.
