    • The invention relates to a glass sheet having a composition that comprises, in an amount expressed in percentages by total weight of glass: SiO2: 55-85%; Al2O3: 0-30%; B2O3: 0-20%; Na2O: 5-25%; CaO: 0-20%; MgO: 0-15%; K2O: 0-20%; BaO: 0-20%; Total iron (expressed in Fe2O3 form): 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 Sb2O3 form), in an amount ranging from 0.01 to 1% by weight; arsenic (expressed in AS2O3 form), 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.
    • 本发明涉及具有以玻璃总重量百分比表示的量的组合物的玻璃片:SiO 2:55-85%; Al2O3:0-30%; B2O3:0-20%; Na2O:5-25%; CaO:0〜20% MgO:0-15%; K2O:0-20%; BaO:0-20%; 总铁(以Fe2O3形式表示):0.002-0.06%; 所述组合物还包含以下组分之一:锰(以MnO形式表示),其量为0.01至1重量%; 锑(以Sb 2 O 3形式表示),其量为0.01至1重量%; 砷(以AS2O3形式表示),其量为0.01至1重量%; 或铜(以CuO形式表示),其量为0.0002至0.1重量%。 本发明还涉及这种玻璃板在使用基本上在所述片材内部传播的红外辐射的装置中的用途。 由于其在红外波长下的高透射率,所述玻璃片可有利地用于例如屏幕或面板或垫中,玻璃板限定触摸表面。
