Two requirements for the pyrometric detection of radiation are the uniform absorption of radiant energy over some desired spectral range, and an observable change of a physical property in response to the increased temperature of the detector resulting from the absorbed radiation. For near UV, visible and near IR measurements, these requirements are embodied in two separate physical phases. For example, a uniform absorber in the form of a carbon black overlayer may be used to coat a thermopile. We have now found that the use of pyrrole polymer can satisfy both these requirements.
