ABSTRACT:
The invention concerns an illumination apparatus for an optical observation device (10), in particular a stereomicroscope or a stereo surgical microscope. A multi-armed light guide with coupler (2) mixes colored light emitted by light-emitting diodes (1a–c) to yield white mixed light (15).
