Abstract
A balancing apparatus for a surgical microscope is suggested balancing an optics carrier with and without a microscope holder holding the surgical microscope and with and without add-on units. The optics carrier is connected via a pivot support to a stand and rotatable around a first rotational axis in relation to the pivot support. The balancing 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. The weight of the second slide acts as a compensation weight for compensating the weight of the optics carrier with and without the microscope holder holding the surgical microscope and with and without the add-on units.
