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.
