The invention relates to an arrangement for a spatially resolved and wavelength-resolved detection of light radiation emitted from at least one OLED or LED. A multilayer system is arranged between an electrode, an OLED or an LED, and a substrate and is formed using layers formed alternately above one another from a material having higher and lower optical refractive indices n. In this respect, light radiation from the at least one OLED or LED and having a plurality of different wavelengths λ1, λ2, λ3, . . . λn thus exits the multilayer system. Light radiation that exits at different wavelengths λ1, λ2, λ3, . . . λn at different angles is incident onto at least one detector array after at least a simple refraction at an optical element or after reflection at a layer or at a layer system of a sensor such that light radiation at a wavelength λ1, λ2, λ3, . . . or λn is incident onto a respective detector element of the detector array. The detector elements of the detector array are arranged discretely from one another.
An arrangement for spatially resolved and wavelength-resolved detection of light radiation emitted from at least one OLED or LED, in which a multilayer system (2) that is formed using layers arranged alternately above one another from a material having a higher and a lower optical refractive index n is arranged between an electrode (3, 4), an OLED (1) or an LED, and a substrate (5), wherein light radiation from the at least one OLED (1) or LED having a plurality of different wavelengths λ1, λ2, λ3, . . . λn exits the multilayer system such that light radiation having different wavelengths λ1, λ2, λ3, . . . λn exits at defined angles and is incident onto at least one detector array (9, 9.1) after at least a simple refraction at an optical element (10, 11) or after reflection at a layer or at a layer system (12.1) of a sensor (12) such that light radiation having wavelength λ1, λ2, λ3, . . . or λn is incident onto a respective detector element of the detector array (9, 9.1) and the detector elements of the detector array (9, 9.1) are arranged discretely from one another.
