标准摘要
[中文适用范围]： 本文件规定了使用带有积分球的双光束分光光度计在 350 nm 至 850 nm 之间的指定波长范围内测定镀膜和未镀膜光学表面的光谱前向散射特性的程序。 该文件也适用于单一波长的前向散射特性。 本文件适用于收集角大于 2.7 度的光谱前向散射测量。 ISO 13696 提供了较小收集角度的测量方法。 [外文原描述]： 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 scattering measurements with collection angles larger than 2,7 degrees. ISO 13696 provides a measurement method for smaller collection angles.
