0.22 NA Silica Core, Glass Clad Multimode Optical Fiber, Step Index




  • 0.22 NA Fiber with Ø50, Ø105, or Ø200 µm Core
  • 250 - 1200 nm or 400 - 2400 nm Operating Wavelength Range

Features

  • Low-OH and High-OH Versions for Different Spectral Ranges
    • High-OH for 250 - 1200 nma
    • Low-OH for 400 - 2400 nm
  • Slilca Core with Fluorine-Doped Glass Cladding

These step-index multimode fibers, manufactured by Thorlabs, are available in three core sizes for a variety of applications. They have a pure silica core with a fluorine-doped silica cladding, and are available with either high or low hydroxyl ion (OH) concentrations for UV to visible or visible to NIR applications, repectively. This fiber is sterilizable by ETO and other methods. These fibers are ideal for applications including spectroscopy for pollution analysis and chemical processing, medical diagnostics, and phototherapy.

Connector Compatibility
The Ø50 and Ø105 µm core fibers sold here have a 125 ± 1 µm cladding diameter, making them compatible with standard single mode connectors and components. We also offer multimode connectors to fit all fibers sold on this page.

Former Generation Product Line
These fibers replace our former generation AFS/SFS series product line, which are available as connectorized patch cables.
