The angular distribution of the light scattered by long, thin glass cylinders was measured at both perpendicular and oblique incidence using a newly designed light-scattering photometer; these results were compared with theoretical calculations. Each set of data could be fit uniquely to a calculated result corresponding to a particular size parameter. The size parameters thus obtained for the same fiber at two wavelengths and several tilt angles agreed with each other.
