Abstract
Abstract An optoelectronic transducer configuration has a radiation-emitting and/or receiving semiconductor component fastened to a carrier plate in such a way that its beam exit/entry face is directed towards the carrier plate. The carrier plate is composed of a material which is transparent to the radiation. A device for focusing the radiation is additionally disposed on the carrier plate. The optoelectronic transducer is distinguished in particular by low reflection losses and simple mounting. A multiplicity of such transducers can be fabricated as a unit and then separated.
