Abstract: An endoscope system includes an illumination section, a color component ratio measurement section and a light quantity ratio adjustment circuit. The illumination section including a light source sequentially or simultaneously radiates an illumination light being a plurality of narrow-band lights having wavelengths different from each other and having light quantities which are independently controllable each other, on an observation object. The color component ratio measurement section measures a color component ratio of the illumination light. The light quantity ratio adjustment circuit adjusts a light quantity ratio of the narrow-band lights based on an output from the color component ratio measurement section and performs color correction to cause the illumination light to be a desired color.

Abstract: An illuminating device includes an illumination pulse generator configured to generate illumination pulses of coherent light, a speckle modulator configured to modulate speckle caused by the coherent light, and a synchronization controller configured to control the illumination pulse generator and the speckle modulator so as to synchronize pulse generation timing of the illumination pulse generator and drive timing of the speckle modulator. The speckle modulator periodically changes a driving intensity of the speckle modulator.

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: A first light source module and an irradiation module are mutually combined. By the combination, illumination light corresponding to a purpose of use is emitted. A relative distance between a light source-side emitter and an irradiation-side incidence entrance in an optical axis direction is adjusted as desired in accordance with the irradiation module, which is connected to the first light source module.

Abstract: An illuminating device includes narrow band light sources including same-color narrow band light sources each configured to emit same-color narrow band light. The same-color narrow band light sources are divided into groups each including at least one narrow band light source. The illuminating device also includes a same-color light source controller configured to control the same-color narrow band light sources and perform light control of emitted light from the same-color narrow band light sources by increasing or decreasing, for each of the groups, an emitted-light quantity of the same-color narrow band light sources within a predetermined reference period, by a unit gradation in a predetermined order.

Abstract: An illumination apparatus includes at least one laser diode, an illumination section, and a light control circuit. The illumination section uses light emitted from the laser diode as illumination light. The light control circuit controls light intensity of the laser diode by pulse-modulating a drive current supplied to the laser diode. The light control circuit controls the light intensity of the laser diode in combination with a duty ratio and a peak current of the pulse-modulated pulse drive current in combination in a multi-oscillation mode region in which a wavelength spectrum width of the light emitted from the laser diode is equal to or larger than a threshold wavelength width.
