Patent ID: 8125708

Claim:
An objective changer for a telescope-type stereomicroscope having a body which houses two telescope systems, and having entrance-side beam paths being oriented parallel to one another, said objective changer comprising: a carrier having a centering element configured to hold the body of the microscope and to align the carrier with the beam paths of the telescope systems; an objective holder which is held at the carrier so as to be movable relative to the carrier between a first stereoscopic working position, a second stereoscopic working position and a third working position; wherein said objective holder has at least a first and a second receptacle for stereo objectives and at least a third receptacle for an additional objective; wherein said two telescope system beam paths penetrate one of the receptacles for the stereo objectives at least in the stereoscopic working positions when the objective changer is arranged at the stereomicroscope; wherein the objective holder is held at the carrier so as to be rotatable around an axis of rotation, the axis of rotation being fixed relative to the carrier in such a manner that the axis of rotation is also fixed relative to the body of the microscope when the objective changer is arranged at the stereomicroscope; wherein the objective holder is held in such a way that a receptacle axis of one of the receptacles and the beam path of the first telescope system are aligned with one another when the objective changer is arranged at the stereomicroscope in at least one monoscopic working position of the objective holder provided by the third working position or another working position; and wherein the axis of rotation is arranged relative to the carrier in such a way that it has different distances from the optical axes of the telescope systems in a plane extending orthogonal to the axis of rotation when the objective changer is arranged at the stereomicroscope.
