Optics and photonics. Spectroscopic measurement methods for integrated scattering by plane parallel optical elements Ingestion-build-190310 Annex E with general remarksWhat is this standard about? 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
