Abstract: An endoscope light source apparatus includes a first light source section that emits first light, a second light source section that emits second light, and an optical path combiner that combines an optical path of the first light and an optical path of the second light. The etendue of the first light source section is smaller than the etendue of the second light source section. The optical path combiner has an optical deflection surface that deflects the second light, and has an aperture that allows the first light to pass through it within an area of the optical deflection surface. The optical path combiner deflects the second light so that a center axis of the optical path of the second light deflected by the optical deflection surface corresponds to a center axis of the optical path of the first light that has passed through the aperture.

Abstract: An endoscope system has observation modes making observations with lights having optical characteristics different from each other. The system includes an endoscope including an insertion section provided with an illumination window, a light guide arranged in the insertion section, and including an entrance end on which the lights enter and a plurality of light guide areas that guide the lights entered on the entrance end, and an entrance area switching unit that switches between the light guide areas through which the entered lights are guided by switching between areas on which the lights enter at the entrance end in accordance with an observation mode.
