    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.

    Abstract: An optical converter is to be simply and reliably monitored. Thereto, a circuit device including a measurement bridge with a measurement branch, a first comparison branch and a second comparison branch is provided. A conductor path loop of the converter can be integrated in the measurement branch. The first comparison branch has a first series resistance variable via a first active element. Similarly, the second comparison branch has a second series resistance variable via a second active element. The first and the second active elements are respectively controllable by the same control signal. The circuit device further has an evaluation circuit with a first comparator and a second comparator, the outputs of which form the control signal and at the same time an output signal of the circuit device in AND-gated manner. Each comparator compares a tap of its respective comparison branch to a tap of the measurement branch.
