Abstract

1 Scope This International Standard gives rules for the measurement of the spectral reflectance of plane surfaces and spectral transmittance of plane parallel elements using spectrophotometers over the spectral range 190 nm to 25 μm. The transmittance τ and the reflectance ρ of optical components are generally divided into two parts as follows:

τ = τ r + τ d (1)

ρ = ρ r + ρ d (2)

where

τ r

is the regular transmittance ;

τ d

is the diffuse transmittance ;...
