Paper Abstract

The origin of scattered light, particularly near-angle scattered light, and its effect on optical resolution have been analyzed. Also, an instrument is described that can measure near-angle scatter. An application of Rayleigh and Mie scattering theories shows that a few large defects cause a high level of near-angle scatter, which leads to a loss of resolution. The degradation in resolution is severe when trying to resolve a bright object near a faint object. A relatively simple apparatus has been built that can measure near-angle scatter at angles as small as 0.03 degrees and at levels of 10-6 peak intensity.
