Abstract

Spectrophotométrie. On éclaire un échantillon de couleur 34 et un échantillon de référence 34a, on dirige la lumière sortant des échantillons vers des spectrographes identiques 40, 42; 41, 43, on disperse cette lumiere en composantes de longueur d'onde que l'on focalise sur la photocathode 44 d'un tube image 30, on évalue l'intensité de ces composantes et on compare les valeurs obtenues pour l'échantillon de couleur et pour l'échantillon de référence à l'aide d'un élément de calcul 45 relié au tube image 30. Evaluation des couleurs, notamment des teintures.
