Fused Silica Quartz Manufacturers at Valley Design

Valley Design produces and stocks wafers and substrates of Fused Silica and Fused Quartz as large as 300mm diameter to 1cm square to as thin as 10-15um thick. Advantages of Fused Silica and Fused Quartz include low thermal expansion, resistance to thermal shock, superior electrical insulation, high transparency from the Ultraviolet light spectrum to the Infrared range, high softening temperature and thermal resistance. Valley Design has thousands of finished Fused Silica wafers available from stock. Single Crystal Quartz is also available lapped, polished, diced and CNC machined.

Valley Design carries and manufactures a variety of fused silica and quartz glass for lighting and semiconductor applications. We can even fabricate gold-coated fused silica quartz tubes for heat-resistant applications in lighting and high-temperature applications.

As a premier fused quartz supplier, we can take any stock fused silica or quartz and manufacture it to your company’s specific needs. Fused silica and quartz glass are also useful in optical applications such as projectors and telescopes, due to its high UV purity grade and ability to be polished smooth.

Among other special properties of fused silica and quartz are three incredible useful characteristics that make fused silica / quartz glass a strong material for its applications:

  • Wide spectral transmission ranges from deep UV to middle IR
  • Laser radiation-resistant
  • High application temperature 1200 degrees Celsius

Valley Design fused silica manufacturers can create and deliver your stock of fused silica and quartz from our high-tech facilities on the east and west coasts.
