Paper Abstract

The scattered light resulting from polystyrene spheres residing on mirrors was measured at λ = 0.6328 μm, and results are compared to that predicted by a modified Mie theory. The method for cleaning the samples, counting and measuring particles, the measurement procedure, and the theoretical model employed to predict the scatter from contaminants on mirrors are discussed. The comparisons between theory and experiment indicate that the theory predicts the forward scatter, but the backscatter predictions are not as successful. The indication is that the developed model can accurately predict the scatter from dust on mirrors.
