Fused silica grades termed UV grade are better controlled from these metals, and so they transmit further into UV ranges. But their drawback is OH caused absorption, especially at 2.2um and 2.7um. All SiO2 glasses share some properties, including extreme hardness, very low thermal conductivity, low thermal expansion, and a wide range of optical transmission from UV to IR.
