1. A hybrid multispectral device, comprising:
a substrate having a first surface and a second surface, wherein the second surface faces away from the first surface, said substrate being a composite substrate and comprising multiple layers;
at least one first functional element having a first functional layer operable to detect or emit light of a first wavelength range, wherein the at least one first functional element is arranged on the first surface of the substrate,
at least one second functional element having a second functional layer operable to detect or emit light of a second wavelength range different from the first wavelength range, wherein the at least one second functional element is arranged on the second surface of the substrate,
wherein the at least one first functional element is arranged in at least one first lateral region of the multispectral device, and the at least one second functional element is arranged in at least one second lateral region of the multispectral device, wherein the at least one first lateral region and the at least one second lateral region are arranged laterally offset from each other in such a manner that the light of the second wavelength range reaches the at least one second functional element or that the light of the second wavelength range emitted by the at least one second functional element exits the multispectral device on the first surface of the substrate without having passed through the first functional layer, and
wherein the substrate comprises a semiconductor substrate on which the at least one first functional element is formed and a glass substrate or a plastic substrate on which the at least one second functional element is formed, and the semiconductor substrate and the glass or plastic substrate are bonded to each other by means of a bonding layer, an adhesive layer or another interconnecting layer.
