Description

Optran® UV optical fibers are multimode fibers with a fused silica core and fluorine-doped cladding, designed for light transmission in the 220–1200 nm spectral range. These fibers represent a standard UV fiber type within the CeramOptec portfolio.

The fiber structure is based on an all-silica design with a defined refractive index profile, enabling controlled light guidance across the specified wavelength range. Optran® UV fibers are available with a range of core diameters and numerical aperture configurations to support integration into different optical systems.

Compared to UVNS fiber types, Optran® UV fibers exhibit similar initial attenuation characteristics, but differ in their behavior under prolonged or high-intensity UV exposure due to differences in preform manufacturing technology.

Optran® UV fibers are used in applications requiring UV transmission under standard operating conditions, where defined optical properties and system integration are the primary requirements.

Frequently Asked Questions

What is meant by a standard UV fiber?
A standard UV fiber refers to a fiber designed for general light transmission within the UV and visible spectral range, without additional design features for enhanced resistance to UV-induced degradation.
How does Optran® UV differ from UVNS fibers?
Optran® UVNS fibers are designed for increased resistance to UV-induced degradation, while Optran® UV fibers are intended for general UV light transmission within their specified wavelength range.
When should Optran® UV be selected instead of UVNS?
Optran® UV is typically selected for applications requiring general UV transmission. For applications involving higher UV exposure or where resistance to UV-induced degradation is critical, Optran® UVNS may be considered.
Which types of applications typically use standard UV fibers?
Standard UV fibers such as Optran® UV are commonly used in spectroscopy, analytical instrumentation, and laboratory systems operating within the UV and visible wavelength range.
Does Optran® UV include features for solarization resistance?
Optran® UV fibers are not specifically designed for enhanced resistance to UV-induced degradation. For applications where this is required, fibers such as Optran® UVNS are typically used.
