Abstract
An endoscope or the like that prevents crosstalk between multiple light-emitting parts is provided. An endoscope includes: an observation window that is disposed at a distal end of an insertion part; a plurality of first light-emitting parts that are disposed around the observation window; a second light-emitting part that is disposed between the first light-emitting parts and emits light at a bandwidth different from a bandwidth of light emitted by the first light-emitting parts; and a light-shielding body that is disposed between one of the first light-emitting parts and the second light-emitting part.
Claims14
An endoscope comprising:
- an observation window that is disposed at a distal end of an insertion part;
- an endoscope illumination substrate having an annular shape;
- a plurality of first light-emitters that are disposed around the observation window;
- a second light-emitter that is disposed between at least two of the plurality of the first light-emitters and emits light at a bandwidth different from a bandwidth of light emitted by the plurality of first light-emitters;
- and
- a light-shielding body that is disposed between at least one of the plurality of first light-emitters and the second light-emitter,
- wherein the plurality of first light-emitters and the second light-emitter are provided along an outer periphery of the endoscope illumination substrate,
- wherein the endoscope illumination substrate includes:
- a base substrate having a mounting surface mounted with light-emitting elements respectively included in the plurality of first light-emitters and the second light-emitter, and
- the light-shielding body stacked on a part of the base substrate on which the light-emitting elements are not mounted,
- wherein the light-shielding body has a light-shielding face that surrounds each of the light-emitting elements in a U-shape that opens to an outer periphery of the insertion part in at least an extension direction of the insertion part, and
- wherein the endoscope illumination substrate is configured to entirely surround the observation window when viewed in a direction orthogonal to the extension direction of the insertion part.
An endoscope illumination substrate, comprising:
- a base substrate having a mounting surface;
- a plurality of first light-emitters on the mounting surface;
- a second light-emitter that is disposed between at least two of the plurality of first light-emitters and emits light at a bandwidth different from a bandwidth of light emitted by the plurality of first light-emitters;
- and
- a light-shielding body that is disposed between at least one of the plurality of first light-emitters and the second light-emitter,
- wherein the plurality of first light-emitters and the second light-emitter are provided along an outer periphery of the annular base substrate of the endoscope illumination substrate,
- wherein the endoscope illumination substrate includes:
- the base substrate having a mounting surface mounted with light-emitting elements respectively included in the plurality of first light-emitters and the second light-emitter, and
- the light-shielding body stacked on a part of the base substrate on which the light-emitting elements are not mounted,
- wherein the light-shielding body has a light-shielding face that surrounds each of the light-emitting elements in a U-shape that opens to an outer periphery of the insertion part in at least an extension direction of the insertion part, and
- wherein the endoscope illumination substrate is configured to entirely surround an observation window when viewed in a direction orthogonal to the extension direction of the insertion part.
