Optran® UVNS – Non-Solarizing UV Fiber (190–1200 nm)

Name: Optran® UVNS – Non-Solarizing UV Fiber (190–1200 nm)
Brand: Ceramoptec
Availability: InStock

Description

Optran® UVNS optical fibers are multimode fibers with a silica core and fluorine-doped cladding, designed for light transmission in the 190–1200 nm spectral range. These fibers are optimized for use in UV applications with increased resistance to solarization compared to standard UV fiber types.

While the initial attenuation characteristics of Optran® UVNS and Optran® UV fibers are comparable, differences in preform manufacturing result in improved performance under higher UV power levels or prolonged UV exposure.

The fiber design provides defined numerical aperture values and stable light guidance across the UV, visible, and near-infrared spectral range. Optran® UVNS fibers are available in a range of core diameters and configurations for integration into optical systems.

These fibers are used in applications where UV stability under higher radiation exposure is required, while maintaining compatibility with broadband transmission requirements.

Frequently Asked Questions

What does “UVNS” mean?

UVNS stands for “ultraviolet non-solarizing” and refers to a fiber design intended to reduce UV-induced degradation compared to standard UV fibers.

How does Optran® UVNS differ from standard UV fibers?

Optran® UVNS fibers show improved resistance to solarization compared to standard Optran® UV fibers, while maintaining comparable initial attenuation characteristics.

Does Optran® UVNS eliminate solarization effects completely?

Optran® UVNS fibers are designed to reduce the effects of UV-induced degradation, but do not eliminate them completely. The level of stability depends on the specific application and operating conditions.

How does Optran® UVNS differ from Optran® UVNSS?

Optran® UVNSS fibers include an additional hermetic carbon layer and stabilization process, extending lifetime under harsh UV or radiation environments beyond the capabilities of standard UVNS fibers.
