Abstract:
(EN) The invention relates to a method for modifying the transmission colour of an optical system 1 having an electrochromic device integrated thereinto. Such a modified optical system makes it possible to combine efficiency of chromatic variation on the one hand while limiting losses in light transmittance on the other hand.
(FR) L'invention concerne procédé de modification de la couleur en transmission d'un système optique 1 intégrant un dispositif électrochrome. Un tel système optique modifié permet d'allier les notions d'efficacité de la variation chromatique d'une part, et de limitation des pertes en transmission lumineuse d'autre part.
