Optran® WFNS – Low-OH Standard NIR Fiber (300–2400 nm)

Name: Optran® WFNS – Low-OH Standard NIR Fiber (300–2400 nm)
Brand: Ceramoptec
Availability: InStock

Description

Optran® WFNS optical fibers have a silica core and fluorine-doped cladding, designed for light transmission in the 300–2400 nm spectral range. The fibers are available with a wide range of core diameters and numerical aperture configurations for integration into optical systems.

Optran® WFNS fibers are low-OH fibers and extend the transmission range into the UV region compared to standard VIS/NIR fibers. They are used in applications requiring broadband transmission from the UV through the visible and into the near-infrared wavelength range.

The fibers can be configured with different numerical aperture values and core/cladding ratios, depending on the application requirements. They are designed for operation across a wide temperature range from -190 to +350°C and can be supplied with various buffer and jacket materials.

Typical applications include spectroscopy, analytical instrumentation, optical sensing, and measurement systems requiring broadband UV–VIS–NIR transmission.

Frequently Asked Questions

How does Optran® WFNS differ from Optran® WF?

Optran® WFNS extends the transmission range into the UV region, starting from 300 nm, while Optran® WF is specified for transmission from 700 nm onwards.

When should Optran® WFNS be selected instead of WF?

Optran® WFNS is typically selected when transmission below 700 nm is required, particularly in applications that include UV wavelengths.

Is Optran® WFNS suitable for UV applications?

Optran® WFNS fibers are designed for transmission starting from 300 nm and are used in applications that include UV wavelengths within this spectral range.

What type of fiber is Optran® WFNS?

Optran® WFNS is a low-OH silica fiber with a fused silica core and fluorine-doped cladding.

Does Optran® WFNS replace UV fibers?

Optran® WFNS extends into the UV spectral range, but it is typically used for broadband applications. Dedicated UV fibers such as Optran® UV or UVNS may be preferred depending on the specific requirements.
