Abstract
Abstract An opto-electronic transducer having a lens-type optical coupling wherein a lens within a lens carrier is arranged in the beam path immediately in front of the transducer. The lens carrier, together with the lens, are fixed to a fastening part by a fastening layer that is adjusted relative to the beam axis of the transducer. The fastening part is part of a common carrier for the transducer. The opto-electronic transducer and the lens carrier together with the lens are secured on the common carrier in such a spacial relationship relative to one another that the beam axis of the transducer is perpendicular to the surface formed by the fastening layer. The opto-electronic transducer of the invention is particularly suited for use as a light waveguide transmission or reception component or, alternatively, as an individual light source.
