Fused quartz polished and shaped wafers and substrates

Fused Quartz and Fused Silica

Wafers, substrates, windows and plates from fused quartz polished to sub-nanometer surface finishes and can be verified by Valley's in-house WYKO non-contact optical interferometer.

For critical applications in:

  • Fused quartz and fused silica flat optical components
  • WDM
  • DWDM
  • MEMS
  • Ultra-thin fused quartz
  • Silicon-on-insulator

Unique services provided include edge/angle polishing, precision dicing, fiber array polishing, ultra-thin components, tight tolerances, super finishes (< 10/5 scratch-dig), long rod end polishing, IC die thinning and other hard to find state-of-the-art solutions. Fused quartz wafers are also available in 300mm diameter to SEMI specifications. Many other sizes are available from stock. Please call or e-mail for a quotation to meet your requirements.
