Fused Silica

OHARA Fused Silica is manufactured according to the VAD method (axial vapor phase deposition). Due to production process our silica shows very good properties regarding high purity, high heat resistance, high transmission and high refractive index homogeneity.

Our Fused Silica is available in the following Standard forms:

  • Tube:           Outer diameters of large size tubes 100~450mm
                         Outer diameters 5~100mm
  • Rods:          Outer diameters 3~200mm
  • Plates:        50~500mm round,50~1000mm sq.

Please see the properties in the following documents for our different types of fused silica (PDF).
