Thumbnail of Optran® PWF – Low-OH Fiber with Silicone Cladding (350-2200 nm) photo 1

Description

Optran® PWF optical fibers are multimode fibers with a silica core and silicone cladding, designed for light transmission in the 350–2200 nm spectral range. These fibers are low-OH fibers, which influences their attenuation characteristics, particularly in the visible and near-infrared wavelength range.

The silicone cladding results in higher numerical aperture values compared to all-silica fiber designs, enabling efficient light coupling and transmission. This makes Optran® PWF fibers suitable for applications where relaxed alignment tolerances or high light collection efficiency are required.

The fibers are available with a wide range of core diameters and numerical aperture configurations, supporting integration into different optical systems. The combination of material composition and geometry provides defined optical performance across the specified wavelength range.

Optran® PWF fibers are used in optical systems requiring efficient VIS and NIR transmission combined with high numerical aperture.

Frequently Asked Questions

What distinguishes Optran® PWF from Optran® PUV?
The main difference between Optran® PWF and Optran® PUV is the OH content. Optran® PWF is a low-OH fiber, while Optran® PUV is a high-OH fiber, which affects their spectral transmission characteristics.
When should a low-OH fiber like Optran® PWF be used?
Low-OH fibers such as Optran® PWF are typically used in applications focusing on the visible and near-infrared spectral range.
Is Optran® PWF suitable for UV applications?
Optran® PWF fibers are designed for transmission starting from 350 nm, but their low-OH composition is typically selected for applications beyond the deep UV range.
What is the role of silicone cladding in Optran® PWF fibers?
Silicone cladding represents an alternative cladding material compared to conventional fiber designs and defines the structural properties of the fiber.
