0.63? Scatter Measurements from Teflon* and Various Metallic Surfaces

Abstract

Angular scatter measurements obtained by illuminating Teflon and various metallic surfaces at normal incidence with a 0.63μ, laser beam are discussed. A method for measuring the scatter in the specular direction is also presented. The measured data are found to be in good agreement with models, which take into account specular reflection, scatter, and absorption. The surfaces investigated were aluminum, steel, brass, first surface aluminized mirror, and aluminized roughened glass surfaces.
