RB Quartz Capillaries

RB Quartz Capillaries are precision-engineered optical components crafted from high-purity quartz, designed for use in advanced optical communication systems. These capillaries boast an exceptional diameter accuracy within ±0.001mm, ensuring high dimensional precision essential for reliable optical performance. Their superior physical and chemical properties, coupled with outstanding ultraviolet transmission capabilities, make them ideal for a variety of optical applications. Specifically, they facilitate the rapid solidification and bonding of single fibers using ultraviolet adhesive, providing a secure and stable connection. The capillaries’ ability to be polished to a degree comparable to optical fibers allows for the easy achievement of the smooth optical surfaces necessary for efficient fiber connections. This makes RB Quartz Capillaries a versatile solution for enhancing the performance of optical connectors, fiber joints, and fiber couplers in sophisticated optical devices.

Features of RB Quartz Capillaries

Features of RB Quartz Capillaries
  • Material: high purity fused quartz, silica (SiO2) content > 99.99%, softening point > 1650℃, high strength, high wear resistance, high transmittance.

  • Properties: The quartz capillary is melted and drawn at high temperature. The surface is transparent, which eliminates local hidden micro-cracks on the surface. It is not easy to crack and break when dispensing glue to fix the optical fiber, and the dispensing qualification rate is high.

  • Quartz capillary is a transparent surface with high ultraviolet transmission characteristics, which can quickly cure and bond the capillary and single fiber through ultraviolet adhesive to fix and position the fiber.

  • Environmental Properties: The production process does not use any chemical solvents, and the materials and production process do not contain or involve substances controlled by the European Union.

  • High dimensional accuracy: Quartz capillaries of various inner hole shapes and structures are accurately made by CNC wire drawing tower, and optical fiber dimensional tolerance and positioning accuracy are high.
