This document specifies procedures for determining the spectroscopic forward scattering characteristics of coated and uncoated optical surfaces over a specified wavelength range between 350 nm and 850 nm using a double beam spectrophotometer with an integrating sphere. This document is also applicable to the forward scattering properties at a single wavelength. This document is applicable to spectroscopic forward
