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.
