Abstract
The invention relates to a glass sheet having high transmission of infrared (IR) radiation. More specifically, the invention relates to a glass sheet having a composition which comprises, in a content expressed as percentages by total weight of glass: SiO55-85% AIO0-30% BO0-20% NaO 0-25% CaO 0-20% MgO 0-15% KO 0-20% BaO 0-20% total iron (expressed in the form of FeO) 0.002-1%, CrO0.001-0.5% Co 0.0001-0.5% Se 0.0003-0.5%. By virtue of its high transmission of IR radiation, said glass sheet can advantageously be used in a device using a technology requiring very good transmission of IR radiation, whether through the main faces or starting from their edge (for example, a screen or panel or pad) The invention thus also relates to the use of such a glass sheet in a device using infrared radiation propagating essentially inside said sheet.
