摘要： An apparatus and a method for producing the apparatus are described, wherein the apparatus includes a substrate with a photodetector and a dielectric arranged on the substrate. Further, the apparatus includes a microlens arranged on a first side of the dielectric. The microlens is configured to steer incident radiation onto the photodetector. Moreover, the apparatus includes a carrier-free optical interference filter. The microlens is arranged between the photodetector and the interference filter, and the interference filter has a plane surface on a side facing away from the photodetector.
