Description

The fiber cables with vacuum feed-through made by Schäfter+Kirchhoff are equipped with polarization-maintaining single-mode fiber cables for wavelengths from 360 to 1800 nm. The feed-throughs are suitable for vacuums down to 10-7 mbar and are supplied with a screw-type flange with thread type M12 x 0.75 mm (nickel silver). It is sealed by a Viton O-ring sealing.

End-to-end fiber cable
All vacuum feed-throughs are supplied with a non-exchangable, continous, end-to-end fiber cable. That means there is no additional fiber connection (mating) at the vacuum flange.

Benefits:

PM fiber cable
On the vacuum side, the fiber cables are equipped with Ø 900 µm buffer made of Hytrel or Nylon. The part of the fiber cable outside the vacuum, has a Ø 3 mm cable with Kevlar strain-relief with bend protection both at the fiber connector and the flange.
The polarization-maintaining fiber cables can be equipped with end caps for reducing the power density at the fiber end-faces.
As an option the connector can be made of amagnetic Titanium (connector type FC only).

Please refer to the individual PMC fiber cable pages for all fiber options. The connector types are described in detail here. 

How to order
For a specific feed-through please contact Schäfter+Kirchhoff. We additionally need information on:

  • Fiber type
  • Cable length inside / outside the vacuum
  • Connector type inside / outside the vacuum
