Abstract

An optoelectronic component can be used for mixing electromagnetic radiation having different wavelengths, in particular in the far field. The optoelectronic component includes a carrier. A first semiconductor chip has a first radiation exit surface for emitting electromagnetic radiation in a first spectral range is provided on the carrier and a second semiconductor chip as a second radiation exit surface for emitting electromagnetic radiation in a second spectral range is provided on the carrier. A diffusing layer is provided on the radiation exit surfaces of the semiconductor chips which face away from the carrier.
