FAQ

What is the primary function of a fluorine-doped quartz tube?
Fluorine-doped quartz tubes are primarily utilized as laser fiber pumped cladding materials. By carefully managing the refractive index profile through high fluorine concentration, they ensure efficient light confinement and maximum energy transmission for high-power laser optical fibers and biomedicine applications.
How does the in-tube chemical vapor deposition (CVD) process benefit the final product?
The advanced in-tube CVD process allows us to achieve an extraordinarily low hydroxyl content alongside a high-concentration fluorine layer. This manufacturing excellence drastically reduces optical attenuation while ensuring good geometric uniformity throughout the entire 800mm length of the tube.
Can the structural dimensions of the fluorine-doped tube be customized?
Absolutely. While our standard tubes feature an outer diameter of 35.5 mm and an inner diameter of 27.5 mm, we offer comprehensive OEM customization. Clients can request customized thicknesses of the fluorine-doped layer, specific numerical apertures (beyond the standard 0.06 ~ 0.24 range), and varying lengths tailored to unique R&D or production blueprints.
Do you offer secondary drawing services for these tubes?
Yes. Beyond providing the preform tubes, Opticlumos is equipped to offer comprehensive fluorine-doped capillary drawing services. This end-to-end capability ensures that the final capillary tubes maintain the exact optical and geometric fidelity engineered into the original preform.
