Amagnetic fiber connectors

Schäfter+Kirchhoff also offers amagnetic FC-APC and FC-PC fiber connectors completely made of titanium and with a ceramic ferrule. This ensures that the relative permeability µr of the connector is near 1 (χ = 5·10^- 5, µr = 1.00005), making it transparent to magnetic fields.

The strengs of a magnetic field or the flux lines and absolute value of the defined magnetic field used in the experiment or application are not perturbed by the fiber connector.

Such highly defined magnetic fields are used for example in Electron Spin Resonance (ESR) or Nuclear Magnetic Resonance (NMR) experiments.

Another application of amagnetic fiber connectors is the highly precise measurement of a magnetic field (magnetometer) where perturbation of the magnetic field by magnetic materials close to the setup is undesirable.

Other amagnetic components are also available, e.g. Laser Beam Couplers or Collimators type 60FC.
