bolometer

A thermometric instrument used for the detection and measurement of radiant energy. Its essential component is a short narrow strip covered with a dead black absorbing coating and mounted at the lower end of a long cylindrical tube having a stop across it to exclude unwanted radiation. The electrical resistance of the strip changes with the changes in temperature that arise from absorbing varying amounts of radiant energy.
