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: SiO2 55-85% AI2O3 0-30% B2O3 0-20% Na2O 0-25% CaO 0-20% MgO 0-15% K2O 0-20% BaO 0-20% total iron (expressed in the form of Fe2O3) 0.002-1%, Cr2O3 0.001-0.5% 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.
