1. An optoelectronic device, comprising:
a substrate with a photosensitive structure,
a dielectric layer on a main surface of the substrate, the dielectric layer having a top surface facing away from the substrate,
at least one wiring layer arranged in the dielectric layer in places,
at least one contact area formed by a portion of the at least one wiring layer,
an opening in the dielectric layer at the top surface, the opening extending towards the contact area,
an optical element arranged on the top surface of the dielectric layer above the photosensitive structure, and
an optical filter arranged on the top surface of the dielectric layer, the optical filter being electrically conductive, covering a portion of the optical element, providing an aperture towards the photosensitive structure, and being in electrical contact with the contact area.
