Fused Silica and Optical Quartz Glass Wafers

Fused Silica and Optical Quartz Glass Wafers (or Substrates) are thin discs or square plates of variable dimensions or shapes made from amorphous form, solid SiO2. Fused Silica, Quartz Glass is a type of glass material with high optical transmission and chemical inertia impressively low thermal expansion, excellent thermal shock resistance, radiation resistance, etc.  The distinctive feature of this material is that it is extremely good at withstanding high temperatures, the maximum limit is up to 1400℃. Therefore fused silica (or quartz glass) wafers and substrates are often incorporated in Spacecrafts. The application fields of quartz glass wafers are also very wide, encompassing UV applications, Optical and Laser Systems, Substrates for semiconductors, microelectronics, Optical Windows, Optical Mirrors, etc. Single crystal quartz wafers are also on sale in Shalom EO.
