Abstract

An instrument has been designed and constructed that can measure the bidirectional reflectance distribution function (BRDF) of optical samples at 10.6 μm, at temperatures of about 85 K, and at pressures near or below 10-6 torr. The results indicate, for the metal mirrors tested, that there is no measurable change in the scattering properties when the temperature is varied from room temperature to cryogenic temperatures.
