Abstract

A conversion device includes a carrier body, a conversion body, which is secured on the carrier body, for converting electromagnetic radiation, a conduction track, which is applied on the conversion body, for monitoring the conversion body, and a contact element applied on the carrier body. The contact element has a first layer construction including at least a first contact layer and a second contact layer including mutually different materials. The conduction track has a second layer construction including at least a first conduction layer and a second conduction layer comprising mutually different materials. The contact element is electrically connected to the conduction track. At least one of the first conduction layer or the second conduction layer are electrically conductive and the thickness of said conductive layers is chosen such that an electrical impedance of the conduction track lies in a predetermined range.
