Synthetic Fused Silica

Fused Silica is a synthetic amorphous silicon dioxide. AGI maintains an inventory of approximately 18,000 lbs of fused silica.  Fused Silica can be made to have the following characteristics:

  • Excellent Homogeneity
  • Bubble and inclusion free
  • Very Low stress Birefringence
  • Good for transmission from the Deep UV to the Near IR
  • Thermally temperature stable
  • Low coefficient of linear expansion
  • Good in three directions
  • High working temperature
  • Knoop Hardness 200gm load 500kg/mm2
  • Standard Optical fabrication techniques can be used to polish

Fused Silica can be used in a wide range of applications:

  • Standard optical components
  • Large laser systems for fusion
  • Spacecraft windows
  • View port windows
  • Micro – lithograph for photo mask and stepper system lenses
  • Test Flats
  • Transmission flats
  • Light pipes
  • Prisms
  • Telescope mirrors
