Description
Leoni Fiber Optics presents its high-quality fused silica tubes, crafted from ultrapure materials to cater to the demanding needs of fiber optic production. These tubes are meticulously designed to serve as the backbone for special fibers, preforms, and optical components, ensuring superior performance and reliability. The purity and precision of these tubes make them an indispensable resource for manufacturers aiming to achieve excellence in their fiber optic products.
The fused silica tubes from Leoni are available in a variety of sizes and dopings, offering unparalleled flexibility for customization. Whether you require undoped tubes with low OH content or fluorine-doped variants with specific refractive index profiles, these tubes can be tailored to meet your exact specifications. This adaptability makes them ideal for creating innovative preform designs and pioneering special fiber technologies.
Among the offerings, the Fluorine-doped fused silica tubes (FST) stand out for their exceptional properties. Developed to meet the stringent requirements of special fiber manufacturers, FST tubes feature high fluorine concentrations, resulting in a negative refraction index delta. This characteristic, combined with low OH content and customizable numerical apertures, makes them an excellent choice for creating sophisticated fiber optic designs. These tubes provide a reliable foundation for preform design, ensuring consistency and precision in fiber optic manufacturing processes.
In summary, Leoni's fused silica tubes offer a robust solution for the production of high-performance optical fibers and components. Their versatility and superior material properties make them a preferred choice for manufacturers seeking to innovate and excel in the field of fiber optics.
