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 fibers with a fused silica core and fluorine-doped cladding, designed for light transmission in the 190–1200 nm spectral range. The fibers are available in a wide range of core diameters and configurations for integration into optical systems.

Compared to standard UV fiber types, Optran® UVNS offers improved resistance to UV-induced degradation, enabling more stable transmission under continuous or high-intensity UV exposure. While initial transmission characteristics are comparable, the fiber design supports enhanced long-term performance in demanding UV applications.

Typical applications include UV spectroscopy, analytical instrumentation, and optical systems operating under elevated UV light levels.

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 are designed for improved resistance to UV-induced degradation. While their initial transmission characteristics are comparable to standard UV fibers, they provide more stable performance under increased UV exposure.

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.

When should Optran® UVNS be selected instead of Optran® UV?

Optran® UVNS is typically selected for applications with higher UV exposure or where long-term transmission stability is important, compared to standard UV fiber solutions.

How does Optran® UVNS differ from Optran® UVNSS?

Optran® UVNSS fibers include additional design features such as a hermetic carbon layer for further enhanced protection, while Optran® UVNS provides improved resistance to UV-induced degradation without this additional layer.
