Product portfolio

A distinction is made between three types of Fused Silica:

  • Fused Silica rods made from undoped silica with a high OH content
  • Fused Silica rods made from undoped silica with a low OH content
  • special dopings, e.g. boron-doped (up to 20wt%) Fused Silica rods

Product properties

  • High homogeneity
  • Low geometric tolerances
  • Low OH content, if required
