Abstract
The invention relates to a glass sheet having a high transmission in the infrared, especially usable in a touch screen, touch panel or touch pad. More precisely, the invention relates to a glass sheet having a composition that comprises, in an amount expressed in percentages by total weight of glass: SiO55-85%, AlO0-30%, BO0-20%, NaO 0-25%, CaO 0-20%, MgO 0-15%, KO 0-20%, BaO 0-20%, Total iron (expressed in FeOform) 0.002-0.06%; and cerum in an amount (expressed in CeOform) ranging from 0.001 to 1%. The invention also relates to the use of such a glass sheet in a device using infrared radiation propagating essentially inside said sheet. By virtue of its high transmission of infrared radiation, the glass sheet according to the invention may advantageously be used, for example, in a screen or panel or tablet, the glass sheet defining a touch surface.
