    Abstract: An illumination apparatus includes a first wavelength converter which absorbs part of the first excitation light and emits first wavelength-converted light, a second wavelength converter which absorbs part of the first excitation light and emits second wavelength-converted light, a reflector including a reflecting surface which is arranged to surround the members, and a holder which holds the members. A first region where light distribution angles of light emitted from the members have a predetermined value or less and a second region where the light distribution angle is less than the predetermined value are present in a region surrounded by the reflecting surface. The holder holds at least one part of the wavelength converter and at least one part of the second wavelength converter at the first region.

    Abstract: An endoscope illumination device includes a light source that outputs primary light, a light guide that includes a first end face from which the primary light is radiated, and guides the primary light, and a light converter that is disposed to face the first end face, includes a second end face which the primary light enters, converts part of the primary light into secondary light. The illumination device also includes a holder that holds the light guide and the light converter so that an incident angle of the secondary light that is radiated from a point of intersection of the second end face and an optical axis of the light guide on the first end face and enters the first end face is equal to or larger than an acceptance angle (NA) of the light guide.

    Abstract: An optical fiber length adjuster includes an entrance and an exit 16 for an optical fiber, and a holding portion to hold the optical fiber so that the optical fiber is deformed. The holding portion is configured to decrease the length of the part of the optical fiber that is held, when tensile force applied to the optical fiber is increased, and increase the length of the part of the optical fiber that is held, when the tensile force applied to the optical fiber is decreased.

    Abstract: An optical device includes a light guiding member that guides light an optical element that functions by being irradiated with the light guided by the light guiding member and a holding member that internally includes a first housing portion housing the light guiding member and a second housing portion housing the optical element and internally holds the light guiding member and the optical element by the first housing portion and the second housing portion so that the light guiding member and the optical element are internally coupled optically. The first housing portion and the second housing portion are communicatively connected inside the holding member and the light guiding member housed in the first housing portion and the optical element housed in the second housing portion are in contact with each other inside the holding member.

    Abstract: An optical connector includes a first engaging member holding at least one first optical fiber to guide light from a light source, a second engaging member holding a second optical fiber to be optically connected to the first optical fiber, and configured to be engaged with the first engaging member, and a light shield member provided near an emission end of the first optical fiber, at such a position as to shield light from the first optical fiber at disengagement of the engaging members. The light shield member is pushed by the second engaging member at engagement of the engaging members, so as to be folded and evacuated in a gap. The light shield member includes a light absorption member to absorb light and to generate heat, a thermal diffusion member to diffuse and radiate the heat, and a base supporting the light absorption member and thermal diffusion member.
