Abstract: An optical system includes an optical assembly including a substrate having two opposite main faces and an electrochemical functional device with electrically controllable optical and/or energetic properties formed on a main face, this optical assembly having an initial color state with an initial color value in reflection at a first reflection angle, a coating for controlling color in reflection formed on the other main face and forming an external face of the system, the optical system having a final color state with a final color value in reflection at this first angle, this final color state being closer than the initial color state to a reference color state having a reference color value at the first angle, this corresponding to a variation in color distance between the initial and reference values, and between the final color and the reference values smaller than 0 at the first angle.

Abstract: A method is directed to modifying the color in transmission of an optical system that incorporates an electrochromic device. Such a modified optical system makes it possible to combine the notions of effectiveness in the chromatic variation on the one hand, and of limitation of losses in light transmission on the other hand.

Abstract: An system includes an optical element including a glazing-function substrate and an electrochromic stack formed on this substrate, this electrochromic stack including a first transparent conductive layer, a working electrode arranged above the first transparent conductive layer, a counter-electrode arranged above said working electrode, a second transparent conductive layer arranged above the counter-electrode, lithium ions introduced into the electrochromic stack, and optionally a separate layer of an ionic conductor, the latter layer being intermediate between the electrode and the counter-electrode, a protective layer arranged on the electrochromic stack, the protective layer including an inorganic lubricating compound.

Abstract: A cathodic subassembly for an electrochromic system, suitable for being deposited on top of a substrate having a glass function, includes a first transparent conductive layer, and a working electrode, arranged on top of the first transparent conductive layer, wherein the working electrode is suitable, by virtue of its chemical composition, for being functional after thermal tempering.
