Abstract: An endoscope includes an observation mode switch to switch observation modes. The observation modes include a dye valid observation mode allowed to acquire an image in which the dye is visually recognized well, and a dye invalid observation mode allowed to acquire an image in which the dye is substantially not visually recognized.

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: A light source apparatus includes a main unit, light source modules attachable to and detachable from the main unit, and storage mediums storing characteristic information of the light source modules. Each light source module includes at least one light source and a light connection part to be optically connected to the main unit. The main unit includes entrance parts to be optically connected to the light connection parts of the connected light source modules, a light combining unit to combine light entering the entrance parts, at least one exit part to cause light combined by the light combining unit to exit, and an exit light characteristic deriving unit to derive characteristic information of achievable exit light based on characteristic information of the light source modules stored in the storage mediums.

Abstract: An endoscope system includes: a light source that is configured to emit primary light; plural illuminators that are configured to be irradiated with the primary light to emit plural respective illumination light generated based on the radiated primary light toward an observation object so that at least part of the plural illumination light overlap on the observation object; and an adjuster that is configured to desirably adjust a ratio of light quantities of the primary light that travels from the light source to the respective illuminators, so as to distribute the primary light to the respective illuminators.

Abstract: A light source illumination unit has operation modes including at least a normal electric power mode to operate with first electric power consumption, and a low electric power mode to operate with second electric power consumption lower than the first electric power consumption. A controller selects at least one of the operation modes in accordance with a use schedule, and controls the light source illumination unit in accordance with the selected operation mode.

Abstract: A first light source module includes a light source-side connection hole to which a irradiation-side connector of a irradiation module is mechanically detachably attached. The light source-side connection hole is made common to the first irradiation-side connector, which is mounted in the first irradiation module, and the second irradiation-side connector, which is mounted in the second irradiation module, such that the light source-side connection hole is connectable to the first irradiation-side connector and the second irradiation-side connector.
