Paper Abstract

Stray light from optical components in BRDF/BTDF measuring instruments is investigated regarding small angle limitations. Angular limits and associated features in the instrument function have been identified. The angular characteristics of the focused laser beam which is specularly reflected/transmitted by the sample are derived in terms of the Gaussian distribution. Measurements of BRDF and instrument function are consistent with the analysis.
