Vacuum Pigtailed Fiber Optic Feedthroughs

High-Performance Hermetic Sealing for UHV & Industrial Applications

Our Vacuum Pigtailed Fiber Optic Feedthroughs provide a robust, leak-proof bridge for optical signals entering high and ultra-high vacuum (UHV) environments. By sealing fibers directly into the flange, we eliminate the need for internal adapters, significantly reducing insertion loss and back-reflection.

We specialise in sealing Single-Mode (SM), Multi-Mode (MM), and Polarization-Maintaining (PM) fibers into precision-machined 304L or 316L stainless steel flanges. Whether you require a single fiber or a high-density multi-channel array, our feedthroughs are engineered for long-term stability in the most demanding vacuum chambers.


Customisation & Integration

Our modular design allows for complete flexibility in hardware and fiber protection:

  • Flange Options: Standard CF, KF, and ISO interfaces, or fully bespoke custom flanges.

  • Protective Tubing: Choose from PTFE, PEEK, or stainless steel jacketing to ensure mechanical durability and environmental resistance.

  • Vacuum Side Terminations: Integrated UHV-compatible connectors (FC/APC, FC/PC, ST/PC, SMA905) or advanced assemblies like V-groove arrays, matrix arrays, and collimators.

  • Atmospheric Side: Support for high-density and standard connectors including LC, E2000, SC, MTP/MPO, and MMC.


Key Advantages

  • UHV Compatibility: Optimised for high and ultra-high vacuum requirements.

  • Multi-Channel Versatility: Individual or grouped fiber sealing within a single flange.

  • Hybrid Solutions: Capability to integrate both electrical and optical feedthroughs in one custom flange.

  • Exceptional Durability: Precision-machined stainless steel construction for high mechanical stability.

  • Broad Compatibility: Supports SM, MM, PM, and POF fiber types.


Critical Applications

Our vacuum-pigtailed solutions are trusted in sectors where failure is not an option:

  • Research & Science: Fusion reactors, particle accelerators, and space simulation chambers.

  • Semiconductor Manufacturing: Optical monitoring and signal transfer within vacuum process tools.

  • Aerospace & Defence: Data transmission for high-altitude and space-grade hardware testing.

  • Advanced Sensing: High-precision spectroscopy and laser signal transmission in controlled environments.
