This document 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 350nm to 700nm, 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 ISO6728 ) throughout this document, the wavelength range reads 370nm to 680nm.
This document is also applicable to mirror lenses (see AnnexA).
