Abstract
The invention relates to a glass sheet having a composition that comprises, in an amount expressed in percentages by total weight of glass: SiO: 55-85%; AlO: 0-30%; BO: 0-20%; NaO: 5-25%; CaO: 0-20%; MgO: 0-15%; KO: 0-20%; BaO: 0-20%; Total iron (expressed in FeOform): 0.002-0.06%; said composition also comprising one of the following components: manganese (expressed in MnO form), in an amount ranging from 0.01 to 1% by weight; antimony (expressed in SbOform), in an amount ranging from 0.01 to 1% by weight; arsenic (expressed in ASOform), in an amount ranging from 0.01 to 1% by weight; or copper (expressed in CuO form), in an amount ranging from 0.0002 to 0.1% by weight. The invention also relates to the use of such a glass sheet in a device employing infrared radiation propagating essentially inside said sheet. By virtue of its high transmission at infrared wavelengths, said glass sheet may advantageously be used, for example, in a screen or panel or pad, the glass sheet defining a touch surface.
