Abstract
A transparency includes a first substrate having a first surface and a second surface. A second substrate includes a third surface and a fourth surface. An optical coating is positioned on the fourth surface. The optical coating having a refractive index of greater than about 1.8 and an nk ratio of greater than about 0.6. The reflectance of the fourth surface has a reflectance of less than about 1.2% as measured from the first surface.
Claims20
An electro-optic element, comprising:
- a first substrate defining a first surface and a second surface;
- a second substrate defining a third surface and a fourth surface, wherein the second and third surfaces are positioned in a spaced apart configuration;
- an electrochromic medium positioned between the first and second substrates;
- an anti-reflective electrode positioned on the second surface comprising a first color suppression layer positioned proximate the second surface and a transparent conductive oxide between the color suppression layer and the third surface;
- and
- a metal layer positioned on the anti-reflective electrode and positioned between the transparent conductive oxide and the electrochromic medium, wherein a reflectance as viewed through the first substrate is about 1% or less.
