Abstract:
The glass is advantageous for microstructuring, especially reactive ion etching with fluorine and fluorine compounds, and has a glass composition based on oxide content and expressed in mol % of: SiO2, 40-70; GeO2, 0-30; B2O3, 5-20; P2O5, 5-20; WO3, 0-10; As2O3, 0-10; Yb2O3, 0-5; and Lu2O3, 0-5. Microstructure components, such as micro arrays, Fresnel lenses, micro wafers, or micro lens wafers, made by a method including reactive ion etching from the glass are also part of the present invention.
