Abstract: A filter assembly includes 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.
