CF and KF vacuum polarization maintaining fiber optic feedthrough with adapter interface

The KTRAV-T12 “CF and KF vacuum polarization-maintaining fiber optic feedthrough with adapter interface” is a multichannel feedthrough. It is available with either a KF flange for high vacuum applications or a CF flange for ultra-high vacuum applications down to 10-11 mbar. And it presents a connector interface on the flange.

Standard configurations are available for:

  • 1 to 4 individual channels within one DN 40 CF flange,
  • 1 to 3 individual channels within one DN 40 KF flange.

Custom designs are also possible upon request as we offer different sizes of ISO, CF, and KF flanges. Consult us for more information.

The channels are soldered to the 304L stainless steel flange, which ensures low outgassing and helium leakage rates compatible with UHV environment. The KTRAV-T12 vacuum polarization maintaining feedthrough ensures a high level of hermeticity better than 10-11 mbar.l/s.

The KTRAV-T12 vacuum fiber feed-through is optimized for polarization-maintaining fibers. It is offered with FC/APC or FC/PC interface.
