Hermetic fiber optic feedthroughs

SEDI-ATI hermetic fiber optic feedthroughs allow to easily deliver optical signals into a vacuum or pressure chamber.

Our broad product range of hermetically sealed fiber optic feedthroughs is well suited for high-vacuum (HV) and ultrahigh-vacuum (UHV) applications as little as 10–8 mbar.l/s. It is also suitable for high-pressure applications up to 1000 bars. For baking-out purposes, temperatures of up to 200 °C can be specified.

We offer different versions for PM, SM and MM fibers. We can achieve multimode feedthroughs with optical fiber core diameters from 50 µm to 1000 µm.

Our product range includes different sizes of ISO, CF and KF flanges. Therefore, our feedthroughs can be easily and steadily mounted on a chamber wall.

SEDI-ATI hermetic fiber optic feedthroughs are available in two main configurations:

  • Bulkhead style; the parts are equipped with standard FC/PC, FC/APC or SMA connectors. This is particularly advantageous to replace sensitive fibers during maintenance work inside the chamber.
  • Inline style; there is no connector at the flange but pigtails terminated with connectors. This solution allows to achieve high packing densities of multiple fibers, at a good price/performance ratio.

We can offer special designs upon request to include customer-supplied specialty fibers, multiple-channel designs, and optical/electrical hybrid feedthroughs.

Besides standard flanges, we can also provide custom-made assemblies with mechanical and optical custom designs to meet your specific requirements.
