With hermetic feedthroughs for optical fibers, optical signals can
easily be delivered into a vacuum or pressure chamber. Laser Components
offers this components for pressures of up to 1000 bar and a vacuum as
little as 10–9 mbar.
Different versions for single-mode and multi-mode fibers of the partner
SEDI Fibres Optiques are available. In multi-mode fibers, core
diameters of 50 µm to 1000 µm can be achieved. In
single-mode fibers, it is possible to also use polarization-maintaining
fibers. FC/PC and FC/APC connectors are available for these fibers; ST
and SMA connectors for the multimode fibers.
Mounting these feedthroughs on a chamber wall is done using a simple
mounting flange that holds the feedthrough steady with a counter nut.
To meet the specifications required of vacuum technology, CF flange and
KF flange versions are also available.
The hermetically sealed feedthroughs are available as coupler and as
inline versions. Special designs that include customer-supplied
speciality fibers, multiple channel designs, and optical/electrical
hybrid feedthroughs are available upon request.
