Abstract
A light source apparatus for an endoscope includes an optical fiber that guides emission light emitted from a light source and is incident on a fiber end face, a ferrule having a ferrule end face having a through-hole in which the optical fiber is inserted, a holder to which the ferrule is fixed, the holder having a reflecting surface that reflects first reflected light to thereby emit second reflected light, the first reflected light being the emission light reflected on the fiber end face, and an optical sensor that receives the second reflected light disposed between the light source and the fiber end face and in a region facing the reflecting surface through an optical axis.
Claims15
A light source apparatus for an endoscope, comprising:
- an optical fiber having a fiber end face, the optical fiber being configured to guide emission light emitted from a light source and incident on the fiber end face;
- a ferrule having a ferrule end face, the ferrule having an opening of a through-hole on the ferrule end face, the optical fiber being inserted into the through-hole;
- a holder to which the ferrule is fixed, the holder having a reflecting surface configured to reflect first reflected light to thereby emit second reflected light, the first reflected light being the emission light reflected on the fiber end face;
- and
- an optical sensor having a light receiving surface configured to receive the second reflected light, the optical sensor being disposed between the light source and the fiber end face and in a region facing the reflecting surface through an optical axis.
An endoscope comprising a light source apparatus for the endoscope, wherein the light source apparatus for the endoscope comprises:
- an optical fiber having a fiber end face, the optical fiber being configured to guide emission light emitted from a light source and incident on the fiber end face;
- a ferrule having a ferrule end face, the ferrule having an opening of a through-hole on the ferrule end face, the optical fiber being inserted into the through-hole;
- a holder to which the ferrule is fixed, the holder having a reflecting surface configured to reflect first reflected light to thereby emit second reflected light, the first reflected light being the emission light reflected on the fiber end face;
- and
- an optical sensor having a light receiving surface configured to receive the second reflected light, the optical sensor being disposed between the light source and the fiber end face and in a region facing the reflecting surface through an optical axis.
An endoscope system comprising an endoscope and a light source apparatus for the endoscope, wherein the light source apparatus for the endoscope comprises:
- an optical fiber having a fiber end face, the optical fiber being configured to guide emission light emitted from a light source and incident on the fiber end face;
- a ferrule having a ferrule end face, the ferrule having an opening of a through-hole on the ferrule end face, the optical fiber being inserted into the through-hole;
- a holder to which the ferrule is fixed, the holder having a reflecting surface configured to reflect first reflected light to thereby emit second reflected light, the first reflected light being the emission light reflected on the fiber end face;
- and
- an optical sensor having a light receiving surface configured to receive the second reflected light, the optical sensor being disposed between the light source and the fiber end face and in a region facing the reflecting surface through an optical axis.
