An optoelectronic component includes a first semiconductor emitter and a second semiconductor emitter, each with an active region configured to generate electromagnetic radiation, and each with a front side coupling out area. The optoelectronic component also includes a radiation-impermeable cover layer and a carrier. The semiconductor emitters are on a first side of the carrier. The first semiconductor emitter is configured to emit electromagnetic radiation in a first wavelength range through its coupling out area. The second semiconductor emitter is configured to emit electromagnetic radiation in a second wavelength range through its coupling out area. The first and second wavelength ranges are different from each other. The cover layer is formed with a photopolymer, is arranged on the first side of the carrier, includes a coupling out window which completely penetrates the cover layer, and in which the coupling out areas are at least partially free of the cover layer.
