Hermetic feedthroughs suit ultrahigh-vacuum applications

Hermetic feedthroughs for multi-mode, single-mode and PM fibres that are suited for high-vacuum, ultrahigh-vacuum and high-pressure applications have been introduced by LASER COMPONENTS.

The direct fibre feedthroughs do not feature a connection option at the flange, making it possible to achieve high packing densities at a good price/performance ratio. The feedthroughs are particularly flexible since the fibres outside and inside the chamber are interchangeable. This is particularly advantageous when using sensitive fibres, or during maintenance work inside the chamber where the connectors can be separated easily.

The feedthroughs are available at different pressure levels from 10-5 to 10-12mbar l/s, and for different ISO flanges. For baking-out purposes, temperatures of up to 180°C can be specified.

Custom assemblies can also be provided, in addition to standard flanges. The mechanical and optical design is customised to meet requirements. A hermetic seal is also available for gases and liquids.
