ELECTRO-OPTIC INFRARED FILTER
First Claim
1. An imaging system, comprising:
- an imager;
an optical lens stack comprising one or more lenses; and
an electro-optic element positioned between the imager and the lens stack, the electro-optic element comprising;
a first substantially transparent substrate defining first and second surfaces, wherein the second surface comprises a first electrically conductive layer;
a second substantially transparent substrate defining third and fourth surfaces, wherein the third surface comprises a second electrically conductive layer;
a primary seal disposed between the first and second substrates, wherein the seal and the first and second substrates define a cavity therebetween; and
an electro-optic medium disposed within the cavity, the electro-optic medium operable between substantially clear and substantially opaque states for at least one wavelength band.

Abstract
An imaging system is provided that includes an imager and an optical lens stack with one or more lenses and an electro-optic element positioned between the imager and the lens stack. The electro-optic element includes a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface has a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed within the cavity. The electro-optic medium is operable between substantially clear and substantially opaque states.
