Electro-optic window assembly
First Claim
1. An electro-optic window assembly, comprising:
- a first substantially transparent substrate comprising;
a first surface,a second surface, anda first peripheral edge;
a second substantially transparent substrate comprising;
a third surface,a fourth surface, anda second peripheral edge,wherein the first and second substrates define a cavity; and
an electro-optic medium at least partially filling the cavity and configured to reduce the transmission of light viewed through the electro-optic window assembly,wherein the electro-optic window assembly is configured such that the substrates each have a theoretical maximum thermal stress of less than approximately 25 MPa upon exposure of the window assembly to an approximately 50°
C. thermal gradient.

Abstract
An electro-optic window assembly is provided that includes a first substantially transparent substrate comprising: a first surface, a second surface, and a first peripheral edge; and a second substantially transparent substrate comprising: a third surface, a fourth surface, and a second peripheral edge. The first and second substrates define a cavity. The assembly further includes an electro-optic medium at least partially filling the cavity and configured to reduce the transmission of light viewed through the electro-optic window assembly. Further, the electro-optic window assembly is configured such that the substrates each have a theoretical maximum thermal stress of less than approximately 25 MPa upon exposure of the window assembly to an application environment.
