ABSTRACT:
A diffuse reflector is provided which isotropically reflects the infrared and far-infrared regions of the spectrum. The reflector includes a metal plate having one surface that is roughened by an electric discharge machine so as to have an r.m.s. roughness large enough to diffusely reflect far-infrared radiation. The roughening process creates facets having cavities which trap and diffusely reflect normally incident far-infrared radiation. An example of a reflector so produced has an isotropic bidirectional reflectance distribution function approximately equal to 1/.pi. sr.sup.-1 between the wavelengths of 5 .mu.m and 100 .mu.m.
