标准摘要
[中文适用范围]： 本文件规定了相机镜头光谱透过率的测量方法。 它描述了在 350 nm 至 700 nm 波长范围内测量主要用于拍摄非常远的物体的相机镜头的轴向光谱透射率的特定条件。 如果整个文件中光谱透射率值专门用于计算 ISO 颜色贡献指数（参见 ISO 6728），则波长范围为 370 nm 至 680 nm。 本文件也适用于镜面镜片（见附件 A）。 [外文原描述]： ISO 8478:2017 specifies a method for measuring the spectral transmittance of camera lenses. It describes particular conditions for measuring the axial spectral transmittance, over a wavelength range from 350 nm to 700 nm, of camera lenses which are intended to be used mainly for taking pictures of very distant objects. If the spectral transmittance values are used exclusively for the calculation of the ISO colour contribution index (see ISO 6728) throughout ISO 8478:2017, the wavelength range reads 370 nm to 680 nm. ISO 8478:2017 is also applicable to mirror lenses (see Annex A).
