Abstract: An endoscope system includes an endoscope including a control section, an insertion section, and a light guide member, a light source configured to emit light guided by the light guide member, a failure-cause detecting circuit configured to detect a pre-failure state that causes a failure of the endoscope, and a light source controller configured to control an output of the light source based on a detection result of the failure-cause detecting circuit. The failure-cause detecting circuit includes a cause predicting circuit configured to detect a second pre-failure state in which it is predicted that the endoscope reaches a first pre-failure state that directly causes the failure of the endoscope. The light source controller controls the output of the light source based on a detection result of the cause predicting circuit.

Abstract: An optical unit includes an optical element serving as a light guide path, which includes an incident entrance, an emitter, a light coupler which is arranged in the case where a plurality of incident entrances are arranged, and which couples a primary light, and a light separator which is arranged in the case where a plurality of emitters are arranged, and which separates the primary light to each of the emitters. The optical unit further includes a detector which directly or indirectly detects a leakage light leaking outside of the light guide path from the light guide path.

Abstract: An illumination device includes a light converter that primary light enters and that is configured to convert at least part of the primary light into secondary light having a second wavelength that differs from a first wavelength of the primary light and to diffuse the secondary light, a first reflector configured to reflect at least part of the diffused secondary light toward the light converter, and a holder holding at least one of the first reflector and the light converter. The first reflector and the light converter are separated from each other so that the primary light transmitted through the first reflector enters the light converter.

Abstract: A light guide unit includes a light guide member and a protection member surrounding the light guide member. The light guide member includes an optical fiber having an outer diameter. The protection member is formed in a network structure by knitting a metal member having a flat cross-sectional shape by bending the metal member in a direction in which the thickness of the metal material is thin, and a gap smaller than the outer diameter is formed along the axial direction.

Abstract: The observation system images a specimen under illumination lights applied at different timings through irradiation windows arranged near one image sensor, generates optical information included in each image, calculates values of light volumes included in the optical information output from identical-point originated pixels, which have imaged an identical point as the same characteristic point on the specimen, in the respective pixels as a relative distance from an image sensor, compares the optical information between the pixels, and determines the identical point on the specimen as a flat surface portion or an inclined portion on the basis of a comparison result, associates the distance with the flat surface portion or the inclined portion, estimates a surface shape of the specimen, and displays a three-dimensional image of the specimen.
