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.

Illuminating device for an operation microscope having optically-coupled observation tubes for a main observer and at least one co-observer and a common objective through which observation beam paths of said main observer and co-observer observation tubes pass, comprising:
- at least one illuminating beam path;
- and
- at least two deflecting elements arranged side by side in said illuminating beam path for deflecting illuminating beam pencils in said illuminating beam path in a direction of an object field,
- said deflecting elements each projecting in a common objective plane to overlap at least partly two observation paths of said main observer and said at least one co-observer nearest to said deflecting elements.
