- a device for measuring minute amounts of radiant energy by determining the changes of resistance in an electric conductor caused by changes in its temperature.

Historical Examples of bolometer
A more careful study has been made by Langley and Very with the bolometer.
Later, Langley reinvestigated the radiation of Pyrophorus and could detect no heating whatever with the bolometer.
We have a heat-measuring instrument, the bolometer, which makes the best thermometer seem Early Victorian.The Outline of Science, Vol. 1 (of 4)
