Description

Configurable Hermetic Fiber Optic Feedthroughs

High-Performance Connectivity for UHV & Positive Pressure

Engineered for the most demanding environments, our hermetic optical feedthroughs provide a reliable bridge between atmospheric and vacuum/pressure environments. These units are fully configurable, allowing you to tailor the adapter interface, fiber type (SM, MM, or PM), and flange design to your precise system requirements.

Built with a rugged stainless steel housing, each feedthrough is helium-leak tested to ensure integrity in Ultra-High Vacuum (UHV) and high-pressure applications.


Key Advantages

  • Universal Connector Support: Fully compatible with FC, ST, and SMA 905 interfaces.

  • Superior Hermetic Sealing: Guaranteed helium leak rates of 10-10 to 10-12 mbar·l/s.

  • Serviceable Design: Features replaceable ceramic mating sleeves and adapter interfaces for extended service life.

  • Versatile Mounting: Available as standalone components or integrated into CF, KF, ISO-K, or custom flanges.

  • Flexible Installation: Choose between permanent welded seals or replaceable Viton O-ring seals for easy maintenance.


Optimised for Extreme Industries

Our hermetic solutions are the industry standard for applications where signal loss and leakage are not an option:

  • Vacuum & Semiconductor: Reliable optical links for cleanrooms and UHV processing.

  • Fusion Research (Tokamaks): High-integrity seals for plasma diagnostics and research.

  • Aerospace & Defence: Designed for the rigors of space-simulated environments and high-altitude flight.

  • Laser & Medical Systems: Secure, high-power optical connections for vacuum-sealed medical and industrial lasers.
