Paper Abstract

Martin Black has been heated to 250 °C in air and the scattering properties at 0.6328 and 10.6 micrometers are described. Significant reductions are seen in the bidirectional reflectance distribution function (BRDF) when the sample is at elevated temperatures. These lower values of the scattering function are seen in both visible and infrared measurements. The reductions in the visible BRDF do not remain after the sample was remeasured after cooling overnight in the normal atmosphere present in the scatterometer. The reduction in the infrared BRDF is however still present in measurements made with the sample at ambient temperature after sitting overnight under the same conditions.
