Abstract
An illuminating device for an endoscope system emits light toward a light receiving surface of an optical fiber bundle. Light incident on the light receiving surface of said optical fiber bundle is emitted from a light emitting surface of the optical fiber bundle for illuminating an object. The illuminating device is provided with a plurality of light emitting elements, each of which emits a directive monochromatic light beam. The light beams emitted by the plurality of light emitting elements are incident on the light receiving surface of the optical fiber bundle within an angular aperture of the light receiving surface thereof.
