摘要： An imaging system is provided that includes an imager, an optical lens stack, and an electro-optic element positioned between the imager and the lens stack. The electro-optic element includes a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface has a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed within the cavity. The electro-optic medium is operable between substantially clear and substantially opaque states.

摘要： An electro-optic assembly includes a first substrate and a second substrate that is disposed in a substantially parallel spaced apart relationship with the first substrate. A first conductive layer is disposed on the first substrate, and a second conductive layer is disposed on the second substrate. A cathodic electro-optic film is in contact with the second conductive layer and includes a cathodic species. An anodic electro-optic film is in contact with the first conductive layer. The anodic electro-optic film includes a plurality of anodic species mixed at a molar ratio that is configured to generally maintain an a* value and a b* value of the electro-optic assembly both staying between −8 and 8 between a high-end transmission state and a fully darkened state caused by an applied voltage range. An electrolyte medium is disposed between the cathodic and anodic electro-optic films.
