Abstract:
A microscope stand for supporting a surgical microscope, said stand having a vertical support (1), a horizontal support (2) pivotable about a rotational axis (30) relative to said vertical support (1), a brake (4) for holding the horizontal support (2) at a selected pivot position relative to said vertical support, and a vibration damper arranged for reducing transmission of angular vibrations between said vertical and horizontal supports (1, 2), wherein the vibration damper is configured as a torsional damping element (5) acting with respect to annular displacements about said rotational axis (30), said torsional damping element (5) having a resilience so great that it brings about at least 90% return of a stand component displaced against the annular direction of action of the torsional damping element when said brake is applied.
