Abstract
A stereomicroscopy system is disclosed for viewing an object and/or an intermediate image produced of an object, in microsurgery. The stereomicroscopy system includes an objective system with an object plane for positioning the object and/or the intermediate image to be viewed. The stereomicroscopy system also includes a beam interchanging and image inverting system. The beam interchanging and image inverting system supplies a first beam bundle directed to the left from the object plane in the direction of the objective system to the right of the objective system. The beam interchanging and image inverting system also supplies a second beam bundle directed to the right from the object plane in the direction of the objective system to the left of the objective system. The beam interchanging and image inverting system also inverts image orientations of the two beam bundles. The beam interchanging and image inverting system includes at least one Porro prism of the second kind.
