Abstract

A light guide for industrial, medical, or cosmetic applications is provided, having an outer circumferential surface and at least one end face made of glass, with an optical element made of at least one transparent plastic directly molded to the end face of glass by molding or reactive injection molding, so that the electromagnetic radiation guided in the light guide when in its operational state is directed through the end face of glass into the transparent plastic of the optical element and exits therefrom.
