ABSTRACT:
A sensor element arrangement for a pyrodetector has a concave mirror with a sensor element arranged at a focus of the concave mirror and further sensor elements arranged laterally therefrom. Electrodes of both polarities are present on each side of the film, these electrodes being respectively separated from one another by quasi-meander-like, metal-free strips which engage into one another in the form of hook portions. The electrodes on the upper side reside opposite corresponding electrodes on the lower side of the formation of the sensor elements, and these electrodes are connected to one another at edge regions by connection lines. The sensor element arrangement together with the film and the connection lines is surrounded by a retaining frame which is insertable into the mounting of the concave mirror in centered and adjusted fashion.
