Fused silica tubes have many uses in the production of specialty fibers. Usually they are a component of an specialty fiber preform. Typical applications include:
Jacket tubes to serve as cladding material
Silica tubes come in many different sizes and the key characteristics are the geometric tolerances, the chemical purity and the OH content.
High purity fused silica tubes
High Purity Fused Silica Tubes for Specialty Fiber Production
For your demanding applications Heraeus offers furthermore a product portfolio of fused silica with special material properties which allow for example a viscosity or refractive index match. These silica tubes are used as substrate material for the core deposition, cladding material or redrawn into capillaries for Photonic Crystal Fibers. For more details, please check the datasheet or contact our experts.
For high power lasers we offer tubes with an inner undoped section as pump cladding for the pump light and a highly fluorine doped fused silica layer to guide the light. The interface between pump area and guiding layer can be round but also shaped to increase the pump efficiency of the laser source. These kinds of tubes are commonly used for higher power lasers with increased power levels.
These tubes have an outer diameter of 1 to 5 mm and a narrow geometrical tolerance. Typical applications include the manufacturing of photonic crystal fiber preforms and fiber combiners. You may order these tubes made from high purity fused silica or in fluorine-doped fused silica. For additional details, please check our datasheet or contact our experts.
