高红外线传输之玻璃片;HIGH INFRARED TRANSMISSION GLASS SHEET

摘要

本发明系关于一种具有高红外线传输之玻璃片。更确切而言，本发明系关于一种玻璃片，其具有包含以下各物质之组成，该等物质之含量以占该玻璃总重量之百分比表示：78<SiO285% 0Al2O330% 0B2O320% 0Na2O25% 0CaO20% 0MgO15% 0K2O20% 0BaO20% 0.002总铁(以Fe2O3形式表示)0.06%，该组成包含诸如0.0001%Cr2O30.06%的以占玻璃总重量之百分比表示的铬含量。因为根据本发明之玻璃片具有高红外线传输，所以其可有利地用于例如萤幕或面板或板中，其中该玻璃片界定触摸感应式表面。本发明亦关于此类玻璃片在使用主要在该薄片内部传播之红外线辐射之装置中的用途。; SiO285% 0Al2O330% 0B2O320% 0Na2O25% 0CaO20% 0MgO15% 0K2O20% 0BaO20% 0.002total iron (expressed in the form of Fe2O3)0.06%, said composition comprising a chromium content such as: 0.0001%Cr2O30.06% expressed in a percentage of the total weight of glass. Because of its high IR transmission the glass sheet according to the invention can be advantageously used, for example, in a screen or panel or pad, wherein the glass sheet defines a touch sensitive surface. The invention also relates to the use of such a glass sheet in a device using an infrared radiation that propagates essentially inside said sheet.
