Hermetic Feedthroughs for Fiber Optics

Sealed in Any Case


To use optical fibers in pressure chambers or vacuum applications, they have to be guided from the outside 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 fibers that are suited for high-vacuum (HV), ultrahigh-vacuum (UHV), and high-pressure applications.

Direct Fiber Feedthroughs
Direct fiber 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:

  • Pressure-tight feedthroughs that are waterproof and airtight
  • HV and UHV-tight fiber feedthroughs

Connector-based Feedthroughs
These versions are particularly flexible since the fibers outside and inside the chamber are interchangeable. This is particularly advantageous when using sensitive fibers or during maintenance work inside the chamber in which 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.
In addition to standard flanges, custom assemblies can also be provided. The mechanical and optical design is customized to meet your requirements. A hermetic seal is also available for gases and liquids.
