Simple expressions for the temperature-dependent absorptivity at 10.6 µm have been computed for silver, aluminum, gold, copper, lead, and tungsten by means of a straightforward application of the Drude model and experimental dc conductivity data over a wide temperature range. The results of these computations are in reasonable agreement with experimental data where such are available.
