Optical fibres used in pressure chambers or vacuum applications have to be guided from the outside then into the inner environment. Feedthroughs that can withstand high pressure and also feature high temperature stability are used for this purpose. We offer a new range of products for multi-mode, single-mode, and PM fibres that are suited for high-vacuum (HV), ultrahigh-vacuum (UHV), and high-pressure applications.
Direct Fibre Feedthroughs
Direct fibre feedthroughs without a connection option at the flange make it possible to achieve high packing densities at a good price/performance ratio. Two versions are available:
1. pressure-tight feedthroughs that are waterproof and airtight
2. HV and UHV-tight fibre feedthroughs
Connector-based Feedthroughs
These versions are particularly flexible since the fibres outside and inside the chamber are interchangeable which is particularly advantageous when using sensitive fibres, or during maintenance work inside the chamber where the connectors can be separated easily. This range of products consists of HV and UHV-suitable connector and coupler-based solutions.
Product Features
Our feedthroughs are available at different pressure levels from 10-5 to 10-12 mbar l/s and for different ISO flanges (e.g., KF and CF 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 your requirements. A hermetic seal is also available for gases and liquids.
