Abstract

A component for the transmission of light of high energy density with a wavelength between 250 nm and 400 nm is made of synthetic, high-purity fused vitreous silica having a hydroxyl ion content in the range between 50 ppm and 1200 ppm and an under-stoichiometric content of oxygen for the achievement of a minimal transmission variation in the transmission of the light.
