ABSTRACT:
The present invention relates to an electro-conductive, anti-reflection coating with the conventional half-wave, high-index layer sandwiched between two quarter-wave, low-index layers, in which the high-index, half-wave layer forms an electro-conductive layer, and in which the layer materials are selected such that an index ratio (high index/low index) is between 1.45 to 1.55 providing wide band widths for the anti-reflection coating. Preferably, the half-wave, electro-conductive, high index layer comprises indium titanium oxide providing a sheet resistance of less than 20 ohms/sq.
