ABSTRACT:
A bolometer which is adapted for a wide-band of radiation including soft adiation, and in which the sensitivity of the time constant (the heat flow from the absorber layer to the dissipator layer) can be exactly preselected without regard to the wave length of the radiation. The bolometer includes an electrically insulating carrier foil which has mounted thereon an absorber layer on one side thereof and a resistance layer on the opposite side of the foil, the resistance layer being part of a resistance measuring bridge. A thermally conductive layer is placed between the absorber layer and the carrier foil. The thermally conductive layer has portions protruding beyond the absorber layer. A heat dissipator is in thermally conductive contact with the protruding portions of the thermally conductive layer to dissipate the heat of the absorber layer. The laterally protruding portions of the thermally conductive layer in contact with the heat dissipator are shielded against the radiation to be measured.
