Abstract

L'invention concerne un colorimètre trichromatique. Le colorimètre comporte une sonde 13 constituée par un guide de lumière comportant un faisceau de fibres optiques 14 et une tige de verre diffusante 39 entourée d'un collier mobile 50 pour éclairer l'échantillon et renvoyer la lumière réfléchie à travers un disque rotatif 16 à écrans rouge, bleu, vert sur une diode photosensible 18, le disque étant synchronisé avec un voltmètre numérique pour afficher les valeurs des densités optiques de l'échantillon pour les composantes rouge, bleue et verte. L'invention vise également un procédé pour prédire la couleur d'un mélange de porcelaine à l'aide de ce colorimètre. L'invention est applicable à la fabrication des dents artificielles.
