Abstract
An infrared emitter is provided. The infrared emitter includes a substrate made of an electrically insulating material. The substrate includes a surface that contacts a printed conductor made of a resistor material that is electrically conducting and generates heat when current flows through it. The electrically insulating material includes an amorphous matrix component into which an additional component is embedded that absorbs in the spectral range of infrared radiation. At least a part of the surface is configured with a cover layer made of porous glass, whereby the printed conductor is embedded, at least in part, in the cover layer.
