Contactlessly operating detectors which are accommodated in a casing provided with a window and which exploit the pyroelectric effect (FIG. 1) are being increasingly used for radiation and temperature measurement. In particular for applications in the infrared range of the spectrum, the manufacture of a suitable absorption layer causes difficulties in achieving the necessary adhesion properties. The absorption layer must have a high degree of adhesion and bonding brought about by gluing, soldering or welding. For this purpose it is proposed that the layer be very thin and comprise a chemically resistant, electrically conductive compound of metals and their oxides such as tin and tin-oxide or silicon and silicon oxide. In addition, these layers are characterized by a degree of surface roughness which is approximately equal to or higher than the wavelength of the radiation to be absorbed.
