Abstract

A component for detecting electromagnetic radiation comprising a first functional layer, in which at least one first element is embodied by which electromagnetic radiation of a first wavelength range can be detected, with the first functional layer being deposited on one side of the substrate. On the opposite side of the substrate a second functional layer is deposited, in which at least one second element is embodied by which either electromagnetic radiation of a second wavelength range can be detected, with the first functional layer and the substrate being transparent with regards to the electromagnetic radiation of the first wavelength range, or by which the electromagnetic radiation of a second wavelength range can be emitted.

First claim
