EAGLE2000 glass is a lightweight AMLCD Alkaline Earth Boro-Aluminosilicate glass from Corning with interesting capabilities. It features a low density, a low coefficient of thermal expansion and is a near zero alkali glass material with a total alkali content of approximately 0,1 wt% (typically <0,05 wt%). The fusion drawn AMLCD glass provides the excellent flatness and a high surface quality that is indispensable for high resolution applications. The low coefficient of thermal expansion, allow the use of EAGLE2000 in COG (chip on glass) processes, and reduces the effect of thermal shock and glass breakage. Corning's EAGLE speciality glass shows an even higher chemical durability than the 1737 or 1737F materials. The high, broadband, color neutral optical transmittance and the low light absorbance in combination with the low specific weight of EAGLE2000 quality glass, make it an ideal solution for many demanding optical applications.
