EAGLE XG® is an alkali-free* alkaline earth boro-alumino-silicate glass made by CORNING®. It is a perfect material for the fabrication of wafer-level optics. The high-quality glass is manufactured by a unique fusion draw process resulting in excellent flatness, smoothness, surface quality, and low nominal thickness tolerance. EAGLE XG® is considered eco-friendly as the glass contains no heavy metals like arsenic, barium, or antimony.
EAGLE XG® glass offers excellent dimensional stability, high chemical durability, and outstanding clarity. It provides all features required for modern LCD-Displays. The thermal coefficient of expansion (CTE) of EAGLE XG® glass closely aligns with silicon, enabling many advanced applications in semiconductor technology. Furthermore, the glass has been optimized for an increased strain point, allowing improved fabrication processes at higher temperatures.
Also, EAGLE XG® is an exciting material for scientific applications. Especially the very low micro-roughness of the glass surfaces allows special research projects impossible with most other glass materials.
