Abstract: A filter assembly includes comprises an incident medium, a spacer, at least one dielectric filter and an exit medium. The spacer is arranged between the incident medium and the at least one dielectric filter such that the incident medium and the at least one dielectric filter are spaced apart by a working distance and thereby enclose a medium of lower index of refraction than the incident medium. The at least one dielectric filter is arranged on the exit medium.

Abstract: A top surface of a substrate is provided with a detection element for detecting electromagnetic radiation. A refractive element is formed by a portion of a cover element, which is attached to the substrate, so that the refractive element is arranged facing the detection element. The refractive element may be arranged within a recess of the cover element, so that a cavity is formed between the detection element and the refraction element.
