Invented in the 1960s for demanding applications in astronomy, ULE ®, or ultra-low expansion glass, is a stable titania-silicate glass that exhibits virtually no dimensional changes over extreme temperature variation, making it the material of choice for reflective telescope optics.

Ultra low expansion glass (ULE) is a registered trademark of Corning Incorporated. ULE has a very low coefficient of thermal expansion and contains as components silica and less than 10% titanium dioxide. Such high resistance to thermal expansion makes it very resistant to high temperature thermal shock.

ULE® Corning Code 7972 Ultra Low Expansion Glass Advanced Optics and Materials ULE® Corning Code 7972 Ultra Low Expansion Glass is a titania silicate glass with unique characteristics that have made it the material of choice in applications ranging from machine tool reference blocks to solid and lightweight mirror blanks for large astronomical

2024年9月30日 · Corning designed EXTREME ULE ® Glass to withstand the highest intensity extreme ultraviolet (EUV) lithography, including high numerical aperture (High NA) EUV, which is rapidly becoming an industry standard. EUV lithography allows manufacturers to use the most advanced photomasks to pattern and print the smallest, most complex chip designs.

The processing and properties of Corning Incorporated’s ultra-low expansion (ULE glass) glasses for use in EUV (extreme ultraviolet) masks is reviewed. The properties reviewed include ULE glass’s coefficient of thermal expansion (CTE), low temperature thermal

ULE ® titania-silicate glass is a zero expansion material made by a flame hydrolysis process. The amorphous ULE ® raw glass materials from CORNING come in large and unshaped glass blocks, the so-called "boules", which allow the manufacturing of components with almost any shape or …
