Abstract
A transparent, laminated window, particularly for use as a vehicle windshield, has improved deicing capability and high luminous transmission and near IR rejection, comprises an optical element having a low sheet resistivity of less than about 6 ohms per square and less than about 11% normal incidence reflection of 400-700 nm wavelength light, such element containing at least two transparent metal layers less than 150A thick which are electrically conductively associated with bus bar(s) and separated by one or more dielectric layers.
