Optical distribution connector and endoscopic system

Provided is a technique for further reducing the scale of an endoscope system. An optical distribution connector according to the present disclosure discloses an optical distribution connector (additional connector) which includes an optical connector portion that is configured to be attachable to and detachable from a processor and realizes an optical connection with the processor, a plurality of medical device mounting portions, each of which is attachable to and detachable from a medical device, and at least one optical element that distributes light emitted from a light source included in the processor in each direction of the plurality of medical device mounting portions. In this optical distribution connector, at least one optical element has a spectral distribution wavelength characteristic defined by the light transmittance and the light reflectance for each of the plurality of wavelength bands of light (see FIG. 5).
