ABSTRACT:
An endoscopic light guide connector of the type which has an input end of a light guide fitted in a light guide rod to be inserted into a connector socket at a connection port of a light source to locate a light pickup end face of the light guide at a light condensing position of a condenser lens of the light source. The light guide connector includes an adaptor pipe which is detachably fitted on a fore end portion of the light guide rod and which is fitted with a corrective lens to adjust angles of incident light rays from the condenser lens of the light source on the basis of a numerical aperture of the light guide for receiving input light rays at a maximum acceptance angle or at angles close to a maximum acceptance angle of the light guide. An adjustor unit fixedly receives the light guide rod and adjusts the distance between the input end of the light guide and the condenser lens.
