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 350 nm to 700 nm, of camera lenses which are intended to be used mainly for taking pictures of very distant objects.<\/p>\n

If the spectral transmittance values are used exclusively for the calculation of the ISO colour contribution index (see ISO 6728 ) throughout this document, the wavelength range reads 370 nm to 680 nm.<\/p>\n

This document is also applicable to mirror lenses (see Annex A).<\/p>\n
