Support
A support is designed to receive an operation microscope. This support has a support column, movable around a rotation axis, with a first carrier arm and a second carrier arm which, with respect to the first carrier arm, can be moved around a first pivot axis and a second pivot axis. A cable connection is provided for producing a restoring force for the second carrier arm, and couples the second carrier arm to a counterweight for producing a restoring force around the second pivot axis. The counterweight is arranged in the region of the support column, to minimize inertial action accompanying a movement of the support around the rotation axis. A freewheel rotary joint is provided in the cable connection to suppress a feedback to the counterweight of a movement of the second carrier arm around the first pivot axis.
