IR grade fused silica differs from UV grade fused silica by its reduced amount of OH ions resulting in higher transmission throughout the NIR spectrum and reduction of transmission in the UV spectrum ( Figure 1 ). OH ions can be reduced by melting highquality quartz or
Fused silica has better performance for UV applications and fused quarts does better in the IR. The link at the bottom gives a nice overview of why they have the names that they do and why they
Fused silica is a good electrical insulator retaining high resistivity at elevated temperatures and excellent highfrequency characteristics. The large band gap inherent in the electronic structure of the siliconoxygen bond results in electrical conduction being limited to current carried by mobile ionic impurities.
Fused SilicaUV. Most customers needs can be met with two standard materials FSUV and FSIR. (amorphous silicon dioxide) is produced synthetically from high purity silicon by flame hydrolysis. It differs by its high UVtransmittance from natural Fused Silica molten from crystalline quartz. Even it is called UVFS normally it is the standard
Fused silica Fused silica (or fused quartz or quartz glass) is a type of glass containing primarily silica (SiO 2) in amorphous (noncrystalline) form. External links. Fused quartzWikipedia
Fused silica is a highly important material for a wide range of optical components for dielectric coatings and is also the most important base material for fiber optics. UV and IRgrade fused silica are available for special applications. High chemical purity is often essential for use in optics.
· Fused silica is the glassy form of quartz and is thus isotropic. It is tough and hard and has a very low expansion. Normal varieties contain water which gives strong absortion in the IR. Waterfree varieties are available. There are different types Fused Silica used for different application. We mainly have three types including JGS1 JGS2 JGS3.
3M fused silica products are optimized for purity and consistency. Our revolutionary furnace design helps prevent raw silica sand from becoming contaminated during processing resulting in a product that is pure. 3M fused silica products are optimized for batchtobatch consistency for a more accurate mold and faster overall production.
· Fused Silica is made from high purity silica using unique fusion technology to ensure the highest quality. Our Fused Silica is over 99 amorphous and has an extremely low coefficient of thermal expansion and high resistance to thermal shock. Fused Silica is inert has excellent chemical stability and has extremely low electrical conductivity.
Fused Silica is resistant to chemicals and high radiation. It had a higher purity to Fused Quartz withstanding temperatures over 1000°C and resistant to thermal shocks. We supply several grades of UV Fused Silica and specifications low cost commercial applications spectroscopic instrument windows and general optical substrates to high

Fused Silica. In APAC Sibelco s Fused Silica is used in high voltage insulators. Fused silica is an angular "shaped" silica produced by grinding and milling high purity silica/ quartz. Fused silica therefore has the same intrinsic properties as any other silica. Its chemical formula is SiO2.
· Chemical Properties Fused Silica Chemical Composition. Translume works with Fused Silica (also called fused quartz). This glass is composed exclusively of highpurity silica (SiO 2) in amorphous (noncrystalline) contrast other common glasses (Pyrex borosilicate sodalime etc.) are mixed composition glassesin addition to SiO 2 they include such ingredients as Na 2 O CaO and

UV Fused Silica Windows feature low distortion excellent parallelism low bulk scattering and fine surface quality. This makes them perfectly suited for a wide variety of demanding applications including multiphoton imaging systems and intracavity laser applications. Extremely low bulk scatter and autofluorescence.
· Crystal quartz is a very useful material for fabrication of finished optics laser beamsplitters AO elements polarizing optics prisms windows lenses in the ultraviolet because of its high UV VIS and NIR transmittance. Fused Silica is used for viewing windows being transparent to wavelengths from around to µm.
Fused silica has better performance for UV applications and fused quarts does better in the IR. The link at the bottom gives a nice overview of why they have the names that they do and why they
Fused silica (fused silicon dioxide) is silica glass (amorphous). In contrast to the presence of other ingredients in common glasses for reducing the melting temperature fused silica has no other ingredient. As a result fused silica has highworking and melting temperatures.
