ABSTRACT:
An endoscope light source apparatus to which a fiberscope or an electronic endoscope can be connected is removably provided with a rotary filter apparatus on an optical axis connecting a light source emanating illuminating light and an illuminating light emanating end for feeding a connected scope with the illuminating light output from the light source. In case the rotary filter apparatus is inserted, the rotary filter apparatus has a rotary filter which sequentially transmits the illuminating light of a specific wavelength from the light source. Furthermore, the apparatus has a plurality of character filters on the optical axis and is provided with a character changing apparatus which changes the character of the illuminating light from the light source by selectively interposing the character filter on the optical axis corresponding to the connected scope.
