Abstract
A variably transmissive electro-optic window that has an easily tunable dynamic range is disclosed. The window comprises a first substrate, a second substrate, a first electrode, a second electrode, an electro-optic medium, and at least one tuning layer. The first substrate has a first and a second surface. The first surface is in a first direction relative the second surface. The second substrate has a third and a fourth surface. The third surface is disposed in the first direction relative the fourth surface. The second substrate is disposed in a second direction opposite the first direction relative the first substrate. The second substrate is additionally disposed in a substantially parallel and spaced apart relationship with the first substrate. The first electrode is disposed in the second direction relative the first substrate. The second electrode is disposed in the first direction relative the second substrate. The electro-optic medium is disposed between the first and second electrodes. Additionally, the electro-optic medium is operable to vary a transmittance of light therethrough. Lastly, a tuning layer is substantially transparent and operable to attenuate the transmit…
