Attention! You can customise this product to your needs.
Fused silica is formed by chemical combination of silicon and oxygen. Advantages of fused silica material includes good UV and IR transmission, low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions, wider thermal operating range and high laser damage threshold. UV grade fused silica offers both highest transmission (especially in deep-UV) and very low fluorescence levels. Used for windows, lenses, prisms and mirror substrates.
