Title

(EN) SILICA GLASS
(FR) VERRE DE SILICE

Abstract:

(EN)A silica glass containing from 3 to 10 mass% of TiO₂, which has a coefficient of thermal expansion from 0 to 100 °C, i.e. CTE_{0 to 100}, of 0 ± 300 ppb/ °C and an internal transmittance per mm in thickness within a wavelength region of from 200 to 700 nm, i.e. T _{200 to 700}, of at most 80%.
(FR)Selon invention, un verre de silice contient entre 3 et 10 % en masse de TiO₂, il possède, d'une part, un coefficient de dilatation thermique compris entre 0 et 100 °C, par exemple, une dilatation thermique allant de 0 à 100, de 0 ± 300 ppb/ °C et, d'autre part, une transmittance interne par minute dans le sens de l'épaisseur, au sein d'une région de longueurs d'onde, comprise entre 200 et 700 nm, par exemple, une transmittance allant de 200 et 700, de 80 % tout au plus.
