High Purity Fused Silica Rods for Production of Optical Fiber Core or Cladding
Fused silica tubes and rods are used in key steps of optical fiber production. Chemical Vapor deposition (CVD) processes rely on high purity and precise geometrical properties of tubes to produce excellent core rods. F300 material with a specified OH content below 1 ppm is the ideal material in the fiber optic community.
This product is a fuly-synthetically fused material and is fabricated using the unique process assuring highest quality from the raw material to the final tube. The product has the characteristics of low bubble content, high geometries accuracy and excellent appearance, which is especially used for the special optical fiber.
