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.

Component for the transmission of light of high energy density with a wavelength between 250 nm and 400 nm, made of synthetic, high-purity fused vitreous silica, with a light input section having a light entry surface, a light output section having a light exit surface, and a light transmission section disposed between the light input section and the light output section, wherein the fused silica has a hydroxyl ion content in the range between 50 ppm and 1200 ppm and an under-stoichiometric content of oxygen.
Method for transmitting light of high energy density with a wavelength between 300 nm and 320 nm comprising
- providing a component made of synthetic high purity fused vitreous silica, with a light input section having a light entry surface, a light output section having a light exit surface, and a light transmission section disposed between the light input section and the light output section, wherein the fused silica has a hydroxyl ion content in the range between 50 ppm and 1200 ppm and an under-stoichiometric content of oxygen, and
- transmitting said light through said component.
Method for expanding a beam of light in a plane perpendicular to the direction of propagation of said beam, comprising
- providing a component made of synthetic high purity fused vitreous silica, with a light input section having a light entry surface, a light output section having a light exit surface, and a light transmission section in the form of a thick walled hollow cylinder disposed between the light input section and the light output section, wherein the fused silica has a hydroxyl ion content in the range between 50 ppm and 1200 ppm and an under-stoichiometric content of oxygen, and
- directing said beam into said light input section.
