Abstract: A balancing apparatus for a surgical microscope is suggested for balancing an optics carrier that is held via a pivot support at a stand. The apparatus comprises a Y displacement unit comprising a first slide for displacement of the optics carrier in a Y direction and a Z displacement unit comprising a second slide for displacement of the optics carrier in a Z direction. Both slides are driven by motors. A selector switch enables an operator to select powering either the first motor or the second motor; and a forward-reverse switch enables the operator to select either the forward or the reverse driving mode for the motor powered by the selector switch and consequently establish the forward or the reverse driving mode for the first or second slide, respectively.
