Fused Silica (SiO2) is a synthetic molten, high purity amorphous quartz glass with exceptional properties. It is used for applications that require a very good thermal stability or whenever a great transparency for wavelengths below the visible spectrum is critical. The material has an extraordinarily high optical transmissivity for ultraviolet light and is often used for UV-applications. Due to its low coefficient of thermal expansion, quartz glass has a very high thermal shock resistance. It can withstand very high operating temperatures. The very good UV-light transparency cannot be outperformed by any other industrial glass material. Likewise, the chemical stabilty of this unique material is one of the best. The material is exceedingly resistant against saline solutions, acids and water. Also the high chemical durability against bases is top class and better than for most other glass materials.
Our quartz glass optics and fused silica components are fabricated out of large non-crystalline silica glass blocks, called quartz glass "boules". This raw material is ground, polished and shaped according to customer's specifications. If required, UV-grade quartz glass or Fused Silica can be selected for a low content of inclusions and/or a high refractive index homogeneity and purity. We are processing many different available quartz glass, fused silica or fused quartz raw materials with different properties from nearly any well-known quartz raw glass supplier worldwide.
