The SQ High OH Fused Silica Rods from Leoni Fiber Optics are expertly crafted from undoped silica, designed specifically for applications within the UV and VIS range. This high-purity material is ideal for the efficient manufacturing of various optical components, including lenses, mirrors, and plates. Its exceptional optical and physical properties, coupled with a high degree of homogeneity in the refractive index, make it a preferred choice for producing special preforms. Utilizing a unique melting technology, the material achieves optimal concentrations of OH and H2, enhancing its transmission capabilities and laser durability.

The production process of these fused silica rods results in a material that offers superior transmission properties in the UV and VIS spectrum. This ensures that the material maintains high laser durability, making it suitable for demanding optical applications. The absence of inclusions and bubbles, combined with a high OH/H2 content, contributes to its excellent UV transmittance and very low fluorescence. Moreover, the material exhibits low residual stress and thermal expansion, alongside high thermal stability, which are critical for maintaining performance under varying environmental conditions.

Leoni Fiber Optics distinguishes its fused silica rods into three categories: SQ, j-plasil, and special dopings like BDSR. Each type is tailored for specific optical needs, with the SQ variant being recognized for its high OH content, making it particularly suitable for UV/VIS applications. These rods are fundamental in the design and production of preforms and the process-controlled manufacturing of optical high-power fibers. The specialized melting technology ensures that the rods meet the rigorous demands of modern optical component production.
