█ VIS/NIR Fiber Optic Feedthroughs on CF

Accu-Glass offers fiber optic feedthroughs with 62.5, 100, 200, 400, 600, and 1000 micron core diameters. These feedthroughs are ideally suited for industrial and/or scientific research applications requiring air-to-vacuum fiber optic transitions/connections. Multimode fibers (both Step and Graded Index types) are hermetically sealed into a stainless steel shell, using the latest in glass-ceramic-metal bonding technology. Standard fiber optic feedthroughs are terminated with premium SMA 905 connectors on both vacuum and air sides. FC and ST connections are also available.
Polyimide buffered optical fiber cable assemblies are offered to meet the rigorous demands of ultrahigh vacuum environments. These optical fibers are of a core-and-cladding composite construction. The core, or the filament that guides the light, consists of a thin strand of high-transmission fused silica. The cladding is an outer layer of doped, lower refractive-index fused silica. This dual-layer design tightly confines light to the fiber's central core, thus delivering the maximum amount of light possible at the fiber's destination. Fiber diameters are closely controlled during the drawing process, allowing fibers to center well in connectors and boast low loss rates.
Graded-index multimode fiber bridges the gap between single-mode and step-index multimode fibers, giving up some bandwidth for ease of termination and light launch. It's more economical than single-mode fiber, and primarily used for data communication (not as useful for power transmission) applications requiring medium run distances of 2 to 15 km lengths.

  • █ High-OH, 200-800nm UV/VIS
    For UV/VIS applications only. Use ≤ 15 meter lengths to avoid high attenuation.
     
  • █ Ultra Low-OH, 400–2200nm VIS/NIR
    For extremely long length VIS/NIR applications. Lowest possible light attenuation.

Notes 
  1. Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -80°C
  2. Bare fiber has a pure fused-silica core, fluorine-doped silica cladding, and Polyimide buffer.
  3. Where core diameter is ≥ 200 µm
  4. Bend radius is expressed as this factor x the core diameter
  5. Dependent on wavelength and fiber size.
  6. Optimized for these two specific wavelengths
  7. Vacuum and air side connectors, cables and couplers are not included with feedthrough and must be purchased separately.
