EAGLE²⁰⁰⁰ glass is a lightweight AMLCD alkaline earth boro-aluminosilicate glass from CORNING with impressive capabilities. It features a small specific weight and a low coefficient of thermal expansion. EAGLE²⁰⁰⁰ has a total alkali content of approximately 0.1 weight-% (typically < 0.05 weight-%). The fusion-drawn AMLCD glass provides the flat, high-quality surfaces essential for high-resolution applications. Due to its small thermal expansion coefficient, glass breakage caused by thermal shock often occurring in semiconductor applications is reduced or eliminated. Hence, EAGLE²⁰⁰⁰ provides the technical capabilities required for COG (chip-on-glass) processes. The specialty glass from CORNING shows even higher chemical durability than the older 1737 or 1737F materials. The excellent broadband and color-neutral transmission and small light absorption, combined with the low specific weight of EAGLE²⁰⁰⁰ quality glass make it an ideal display glass solution and enable demanding optical and optoelectronic applications.
