ELECTRO-OPTIC ELEMENT WITH HIGH DOUBLE IMAGE RATIO
First Claim
1. A variable transmittance electro-optic assembly, comprising:
- a first partially reflective, partially transmissive substrate defining a first surface and a second surface;
a second partially reflective, partially transmissive substrate defining a third surface and a fourth surface, wherein the first substrate and the second substrate are configured to be held in a parallel spaced apart relationship and sealed about a perimeter of the first and second substrates;
an electro-optic material positioned between the second surface and the third surface, wherein the electro-optic assembly includes a principle transflector having a transflector coating on at least one of first and second surfaces;
low reflectance coatings disposed on secondary surfaces of said variable transmittance electro-optic assembly, such that the electro-optic assembly has a high double image characteristic defined by a ratio of a reflectance of the transflector coating to a net reflectance of at least one of the secondary surfaces, and further wherein the ratio is greater than 50.

Abstract
A variable transmittance electro-optic assembly includes a first partially reflective, partially transmissive substrate defining first and second surfaces. A second partially reflective, partially transmissive substrate defines a third surface and a fourth surface. The first substrate and the second substrate are configured to be held in a parallel spaced apart relationship and sealed about a perimeter of the first and second substrates. An electro-optic material is positioned between the second surface and the third surface. The electro-optic assembly includes a principle transflector having a transflector coating on at least one of first and second surfaces. Low reflectance coatings are disposed on secondary surfaces of the variable transmittance electro-optic assembly. The electro-optic assembly has a high double image characteristic defined by a ratio of a reflectance of the transflector coating to a net reflectance of at least one of the secondary surfaces, and further wherein the ratio is greater than 50.
