Thumbnail of Optran® WF – Low-OH Silica Fibers for VIS-NIR (700–2400 nm) photo 1

Description

Optran® WF fibers are designed for light transmission in the NIR spectral rangeand are commonly used in NIR Laser Applicarions. Optran® WFNS extends theusable spectral range down to 300 nm, enabling applications that requiretransmission from the UV to the near-infrared.

Optran® WF fibers are low-OH fibers with a hydroxyl content typically below 1 ppm, with lower levels available upon request. They are used in applications focusing on the visible and near-infrared wavelength range and represent a standard fiber type for VIS/NIR transmission within the specified spectral range.

The fibers are available with numerical apertures ranging from approximately 0.12 ± 0.02 to 0.28 ± 0.02 and can be configured with different buffer and jacket materials including silicone, hard polymer, polyimide, ETFE, nylon, and acrylate.

Standard proof test levels include up to 100 kpsi (nylon, ETFE, acrylate) and 70 kpsi (polyimide). The fibers can be used in spectroscopy, analytical instrumentation, optical sensing, and measurement systems operating in the VIS/NIR wavelength range.

Frequently Asked Questions

How does Optran® WF differ from Optran® WFNS?
Optran® WFNS fibers extend the transmission range further into the UV region, starting from 300 nm, while Optran® WF fibers are specified for transmission from 700 nm onwards.
What does “low-OH” mean in the context of Optran® WF?
Low-OH refers to a reduced hydroxyl content in the fiber material, which influences the transmission behavior in different wavelength regions, particularly in the infrared.
When should Optran® WF be selected?
Optran® WF is typically selected for applications requiring transmission in the visible and near-infrared range without the need for extended UV transmission.
Is Optran® WF suitable for UV applications?
Optran® WF fibers are not specified for UV transmission below 700 nm. For applications requiring extended UV transmission, fibers such as Optran® WFNS may be considered.
