Abstract
An optical waveguide serves for guiding illumination light. The waveguide has a waveguide main body for guiding the illumination light between a main body entrance region and a main body exit region. At least one coupling-out device is provided in the main body exit region. Via the coupling-out device, at least one coupling-out illumination light partial beam is coupled out from the illumination light emerging from the waveguide main body. This is done such that the coupling-out illumination light partial beam can be separated from the rest of the illumination light beam emerging from the waveguide main body. This results in a waveguide having improved possibilities for use when guiding illumination light.
