Abstract
An illumination system for endoscopes has a light guide bundle constructed and arranged to illuminate an object to be observed. The light guide bundle is extended in an axial direction of the endoscope and branched into a plurality of branch portions in a frame which is adapted to be disposed inside of the endoscope. Each of the branch portions have a crescent-shaped cross-section at a mid-portion along the axial direction of the endoscope and each of the branch portions have at least one bent portion in which a protective glass plate is disposed on each exit surface of the branch portions. An endoscope system includes the above illumination system.
