Abstract
Abstract An optoelectronic module is disclosed comprising an optoelectronic component (D), e.g. a photodiode (D) and/or a laser diode (D); a ring (RI) as an optical aperture in a wall of its housing (S/E/P, S/G/W) for the transmission of information-modulated light to or from the component (D) through the housing wall (S) to or from an optical component (L); and a lens system (K) having at least one lens (K), among them, at least one focusing lens (K) encircled by the ring (RI) or at least by a section of the ring (RI). At least one of the lenses (K) consists of glass and is intergrown with the ring (RI), at least in part consisting of glass, so as to be hermetically tight all around forming an intergrowth zone (SZ). Furthermore, the ring (RI) is inserted in the housing wall so as to form a hermetically tight seal.
