Abstract
A variable transmission window includes a first substrate having a first transparent conductor coated surface and a second substrate having a second transparent conductor coated surface. The second substrate is positioned relative to the first substrate with the first and second transparent conductor coated surfaces facing each other. An electrochromic medium is disposed between the first and second substrates whereby the transmission of light through the electrochromic medium is changed when an electrical potential is applied thereto. The electrochromic medium includes a cross-linked film. The window may be one of (i) an aeronautical glazing and (ii) a vehicle glazing, and/or the window may be a large area glazing of an area of at least 99 square inches.
