Abstract: An endoscopic system includes a speckle reduction unit which is reduce speckle generated on an observed portion by light that has coherence, a controller which controls an operation of the speckle reduction unit and a plurality of observation modes including a speckle observation mode of observing the observed portion based on the speckle generated on the observed portion by the light. The controller controls the operation of the speckle reduction unit in accordance with the observation modes such that the speckle reduction unit does not reduce the speckle in the speckle observation mode and the speckle reduction unit reduces the speckle in the observation modes other than the speckle observation mode.

Abstract: A light source apparatus includes a primary light source that emits primary light, a diffusing member that diffuses and converts the primary light into diffused light, a reflection portion that regularly reflects or diffuse-reflects and converts the diffused light into reflected light, and an emission portion that emits the reflected light to an outside. A portion of the primary light is converted in an order of the diffused light and the reflected light and emitted to the outside from the emission portion in a state of the reflected light.

Abstract: The wavelength conversion member includes a plurality of fluorescent members that absorb the excitation light and emit fluorescent light having a peak wavelength different from the peak wavelength of the excitation light. The wavelength conversion member has a surface irradiated with excitation light that faces an excitation light emitting surface of the excitation light source. The optical axis passes the center of the surface irradiated with excitation light. The plurality of fluorescent members are arranged in a divisional manner at such proportions that a circumferential area ratio, which is defined as the ratio of area occupied by each of the fluorescent members in a concentric annular region having a center located at the center of the surface irradiated with excitation light on the surface irradiated with excitation light of the wavelength conversion member, is substantially constant irrespective of the radius of the concentric annular region.
