Abstract
An apparatus to provide white illuminating light for medical or boroscopic applications includes a first light source with a light-emitting diode to emit light with a broad spectrum, a second light source to emit monochromatic light, and a coupling device to couple light of the first light source and light of the second light source into a common beam path in order to generate illuminating light with improved color rendering.

An apparatus to provide white illuminating light for medical and boroscopic applications, with:
- a first light source with a light-emitting diode, to emit light with a broad spectrum;
- a second light source to emit monochromatic light;
- a coupling device to couple light of the first light source and light of the second light source into a common beam path in order to generate illuminating light with improved color rendering.
A method to provide white illuminating light for medical and boroscopic applications, with the following steps:
- generate light with a broad spectrum by means of a first light source, which includes a light-emitting diode;
- generate monochromatic light by means of a second light source;
- couple light of the first light source and light of the second light source into a common beam path by means of a coupling device in order to generate illuminating light with improved color rendering.
