Abstract

A sensor element for detecting electromagnetic radiation, particularly in the infrared range, comprises one or more heat-sensitive portions provided on a substrate and one or more influencing layers for influencing the absorption and/or reflection of the electromagnetic radiation to be detected. The heat-sensitive portion(s) and/or the influencing layers are arranged on the substrate in accordance with the thermal properties of the influencing layers, preferably asymmetrically.
