A panorama head for positioning optical equipment precisely relative to a system of axes comprises an articulated joint for each axis, each articulated joint including first and second joint elements which are coupled with one another for rotation about the corresponding axis and can be clamped selectively in the preselected relative angular position; each articulated joint comprises a kinematic reduction coupling with first and second coupling elements which are fixed to the first and second joint elements, respectively, during rotation about the corresponding axis and are movable between a position of mutual coupling for precision adjustments and a position of mutual disengagement for quick positioning. |
