Abstract
For optimizing the perception of the red reflex in eye operations, deflecting elements are arranged in the illuminating beam path in the illuminating device of an operation microscope with optically-mechanically coupled observer and co-observer tubes. The deflected illuminating beam pencils overlap, at least partially, the main observer observation beam paths and at least one of the co-observer observation beam paths.
