Abstract

The invention is directed to a double microscope for a surgeon and an assistant. The double microscope includes an optical splitter plate which splits the light coming from the operation field and directs the split beams to the two microscopes. The optical splitter plate, together with the objective of the assistant microscope and a beam deflection element, are all accommodated in a component connecting the two microscopes.
