Stereomicroscopy system

A stereomicroscopy system for viewing an object or an intermediate image produced of an object, in particular in microsurgery, comprising:

• an objective system with an object plane for positioning the object or intermediate image to be viewed, a left ocular system and a right ocular system;
• and
• a beam interchanging and image inverting system which supplies a first beam bundle entering the objective system on the left to the right ocular system and a second beam bundle entering the ocular system on the right to the left ocular system and inverts image orientations of the two beam bundles;
• wherein the beam interchanging and image inverting system comprises a pair of shortened Porro prisms of the second kind.

A stereomicroscopy system for viewing an object or an intermediate image produced of an object, in microsurgery, comprising:

• an objective system with an object plane for positioning the object or intermediate object to be viewed;
• a left ocular system, to which a first beam bundle is supplied which enters the objective system on the left;
• and
• a right ocular system, to which a second beam bundle is supplied which enters the objective system on the right;
• and
• a beam interchanging system in the beam paths of the left and right ocular systems, said beam interchanging system reflects the first beam bundle supplied to the left ocular system into the right ocular system and for reflecting the second beam bundle supplied to the right ocular system into the left ocular system;
• wherein the first and second beam bundles supplied to the beam interchanging system and the first and second beam bundles emerging from the beam interchanging system have the same image orientations.
