Vacuum Feed-Throughs V-KF50

with two-fold fiber cable

Features

Vacuum flange type KF50 with two integrated fiber cables
  • Based on small flange KF50 (stainless steel)
  • Suitable for vacuums down to 10-7 mbar
  • Incorporated two single feed-throughs type V-SF-PMC, V-SF-SMC, or V-SF-MMC
  • Different connector types

Description

The two-fold vacuum feed-throughs made by Schäfter+Kirchhoff are equipped with two identical or two different fiber cables. The fibers can be polarization-maintaining, single-mode or multimode fibers. The double vacuum feed-throughs are suitable for vacuums down to 10-7 mbar and are supplied with a small flange KF50 (DIN 28403 and ISO 2861, stainless steel).
The feed-throughs incorporate two single feed-throughs type V-SF-PMC, V-SF-SMC, or V-SF-MMC.

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

Benefits:

Fiber cable
On the vacuum side, the fiber cables are equipped with Ø 900 μm buffer made of Hytrel, Nylon or Tefzel. The parts of the fiber cables outside the vacuum, have a Ø 3 mm cable with Kevlar strain-relief with bend protection both at the fiber connector and the flange.

Polarization-maintaining fiber cables and single-mode fiber cables can be equipped with end caps for reducing the power density at the fiber end-faces.
For single-mode fiber cables, the connector away from the vacuum can be core-aligned as an option.
As an option the connector can be made of amagnetic Titanium (all fiber types, but connector type FC only).

Please refer to the individual PMC fiber cable pages, SMC fiber cable pages, and MMC 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 types
  • Cable lengths inside / outside the vacuum
  • Connector types inside / outside the vacuum

The feed-through can be equipped either with two identical or two different fiber cables.
An example configuration can be found here.
