Abstract: A light source device includes a first semiconductor light source, a second semiconductor light source, and a wavelength converter. The first semiconductor light source emits light in a first wavelength range. The second semiconductor light source emits light in a second wavelength range different from the first wavelength range. The wavelength converter absorbs the light in the first wavelength range to emit light in a third wavelength range different from either of the first wavelength range and the second wavelength range, and transmits the light in the second wavelength range substantially entirely.

Abstract: An endoscope light source device includes a light source device and a light source controller. A first light and a second light are narrow band light in a blue region. A third light is in a green region. A fourth light is in a red region. A first light amount ratio is a ratio of a sum of the light amounts of the first light and the second light, the light amount of the third light, and the light amount of the fourth light. A second light amount ratio is a light amount ratio of the first light and the second light. The light source controller adjusts the light amount ratio of the first light and the second light to achieve the second light amount ratio so as to adjust the color representation from a yellow region to a red region in an image of an object.

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 at least four narrow band light sources, primary light combiners that combine narrow band light from at least two of the narrow band light sources, and a secondary light combiner that combines primary combined light combined by the primary light combiners. The device is configured to radiate, as illumination light, secondary combined light combined by the secondary light combiner. The light sources are grouped into groups based on illumination characteristics of the narrow band light so that light sources satisfying a condition for the illumination characteristics are grouped into the same group. The light sources in the same group are connected to the primary light combiners so that the light sources in the same group are distributed to the primary light combiners.

Abstract: An endoscope includes an illuminator to emit illumination light comprised by narrow band lights different in wavelength from an end portion of the endoscope and an imager to image an observation object illuminated by the illumination light emitted from the illuminator. The illuminator includes a light quantity output adjuster to independently control the light quantity of each of the narrow band lights. The endoscope allows observation in three types of modes of a white light mode, a special light mode, and a hybrid mode. A spectral pattern of illumination light in the hybrid mode includes at least a part of a color region of a narrow band light included in the special light mode and is different from either of a spectral pattern of illumination light in the white light mode and a spectral pattern of illumination light in the special light mode.
