Optics and optical instruments. Test methods for radiation scattered by optical components Ingestion-build-133579 4 Initial measurement and functional1 Scope This International Standard specifies procedures for the determination of the total scattering by coated and uncoated optical surfaces. Procedures are given for measuring the contributions of the forward scattering and backward scattering to the total scattering of an optical component. This International Standard applies to coated and uncoated optical components with optical surfaces that have a radius of curvature of more than 10 m. The
