EAGLE2000 glass is a lightweight AMLCD alkaline earth boro-aluminosilicate glass from CORNING with exciting capabilities. It features a small specific weight and a low coefficient of thermal expansion. EAGLE2000 near zero alkali glass material has a total alkali content of approximately 0,1 weight-% (typically < 0,05 weight-%). The fusion-drawn AMLCD glass provides the excellent flatness and high surface quality that is indispensable for high-resolution applications. Due to its low coefficient of thermal expansion, glass breakage caused by thermal shock often occurring in semiconductor applications is reduced or eliminated. EAGLE2000, therefore, has the properties mandatory to be used for in COG (chip on glass) processes. EAGLE2000 specialty glass from CORNING shows even higher chemical durability than the older 1737 or 1737F materials. The high broadband and color neutral transmission and the low light absorption in combination with the low specific weight of EAGLE2000 quality glass make it an ideal solution for displays as well as for demanding optical and optoelectronic applications.
