    Abstract: An endoscope system includes: an excitation light source to emit excitation light; non-excitation light sources to emit non-excitation light; an optical combiner configured to integrate optical paths of the excitation light and non-excitation light into a common optical path; and a wavelength conversion unit including a wavelength conversion member disposed on the common optical path. The wavelength conversion member transmits the non-excitation light, absorbs part of the excitation light to generate wavelength-converted light, and emits illumination light including the non-excitation light and wavelength-converted light. Spectra of the non-excitation light each have a peak wavelength in a wavelength band out of a wavelength band of a spectrum of the wavelength-converted light.

    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: An illumination unit includes a light guide to guide primary light, a conversion member to convert the primary light into secondary light, and a holder holding an exit end of the light guide and the conversion member. The holder includes an entrance portion that the primary light enters, an exit portion to emit illumination light including the secondary light, and a fixing portion fixing the conversion member between the entrance portion and the exit portion in a direction of a central axis of the primary light. The fixing portion is arranged in a planar region perpendicular to the central axis of the primary light and on an inner peripheral face of the holder. The conversion member is in contact with the fixing portion.

    Abstract: An illuminating device includes a light source unit configured to emit primary light, and an illuminating unit configured to generate illumination light based on the primary light. The illuminating unit includes a light converter configured to convert optical characteristics of the primary light. The light converter includes a light transmitter through which the primary light is transmitted, and a light diffuser formed within the light transmitter. The light diffuser is configured to diffuse part of the primary light, generating secondary light included in the illumination light. The light diffuser has a refractive index different from a refractive index of the light transmitter. The light diffuser has a hole formed within the light transmitter, a refractive index-modifying portion, or a crack portion.

    Abstract: A lighting unit includes a single core optical fiber, a light converter, and an exit end. The single core optical fiber includes an incident end and a distal end, and is configured to guide primary light, which is a laser light incident on the incident end, to the distal end. The light converter is formed inside the optical fiber, and is configured to receive the primary light guided by the optical fiber, convert optical properties of at least part of the received primary light and generate secondary light. The exit end is arranged at the distal end of the optical fiber, and is configured to emit the secondary light externally as illumination light.
