With the hermetic feedthroughs for optical fibres, optical signals can be easily delivered into a vacuum or pressure chamber. Pressures of up to 1000bar and a vacuum as little as 10–9 mbar are not a problem.

Different versions for single-mode and multi-mode fibres are available. In multi-mode fibres, core diameters of 50µm to 1000µm can be achieved. In single-mode fibres, it is possible to also use polarisation-maintaining fibres.

Standard feedthroughs are available with the following connectors:

• FC/PC and FC/APC connectors in SM and PM fibres
• ST and SMA connectors in MM fibres

Mounting these feedthroughs on a chamber bulkhead is achieved using a simple mounting flange that holds the feedthrough in place with a counter nut.  To meet the specifications required of vacuum technology, our product range was expanded to include CF flange and KF flange versions.

The hermetically sealed feed-throughs are available as coupler and as in-line versions. Special designs that include customer-supplied specialty fibres, multiple channel designs, and optical/electrical hybrid feedthroughs are available upon request.
