Thumbnail of Optran® PUV – High-NA Fiber with Silicone Cladding (350-2200 nm) photo 1

Description

Optran® PUV optical fibers are multimode fibers with a silica core and silicone cladding, designed for light transmission in the 350–2200 nm spectral range. The fibers are characterized by a high OH content, influencing their transmission behavior in the ultraviolet and visible wavelength range.

The use of silicone cladding represents a distinct fiber design compared to all-silica or fluorinated acrylate cladding structures. This configuration results in higher numerical aperture values, supporting efficient light coupling and collection in optical systems.

Optran® PUV fibers are available with a range of core diameters and numerical aperture configurations, allowing integration into different system designs. The fiber structure enables light transmission across UV, VIS, and NIR wavelengths while maintaining defined guiding properties.

These fibers are used in applications requiring efficient light collection or delivery, particularly where higher numerical aperture is advantageous.

Frequently Asked Questions

What distinguishes Optran® PUV from standard silica fibers?
Optran® PUV fibers use a silicone cladding instead of a conventional silica or fluorinated acrylate cladding, resulting in a different fiber structure.
What is the difference between Optran® PUV and Optran® PWF?
The main difference between Optran® PUV and Optran® PWF is the OH content. Optran® PUV is a high-OH fiber, while Optran® PWF is a low-OH fiber, which influences their spectral transmission characteristics.
Is Optran® PUV suitable for UV applications?
Optran® PUV fibers are designed for transmission starting from 350 nm and are used in applications that include UV wavelengths within this spectral range.
How does silicone cladding affect the fiber design?
Silicone cladding represents an alternative cladding material compared to conventional fiber designs and defines the mechanical and structural properties of the fiber.
When should Optran® PUV be selected?
Optran® PUV is typically selected when a silicone-clad fiber design is required in combination with transmission in the UV, visible, and near-infrared spectral range.
