Description

UHV-Compatible Fiber Optic Patchcords & Pigtails

High-Integrity Light Transmission for Ultra-High Vacuum Systems

Our ultra-high vacuum (UHV) compatible patchcords and pigtails are specifically engineered for seamless data and light transmission within high-vacuum environments. Every assembly is manufactured using strict UHV-compliant processes, utilising low-outgassing adhesives to maintain chamber purity and vacuum integrity.

Our vacuum patchcords are designed for direct integration with UHV fiber optic feedthroughs and adapters, providing a complete end-to-end solution for scientific and industrial vacuum systems.

Precision Engineering for Extreme Environments

To ensure long-term reliability in the most demanding conditions, we offer a range of specialised materials and configurations:

Premium Materials: Terminated with Stainless Steel 304L connectors for maximum corrosion resistance and vacuum compatibility.
Fiber Protection: Specialised jacketing options including Polyimide, PTFE, or Stainless Steel loose tubes to provide mechanical protection without compromising vacuum levels.
High-Temperature Performance: Specialised versions available for high-heat applications, rated for continuous operation up to 180°C.
Custom Fiber Types: Fully optimised solutions available for Single-Mode (SM), Multi-Mode (MM), and Polarization-Maintaining (PM) fibers.

Key Advantages

Standard & Precision Interfaces: Compatible with FC/PC, FC/APC, or SMA 905 connectors.
UHV Optimised: Low outgassing and high mechanical stability for high-vacuum chambers.
Bespoke Lengths: Manufactured to your exact optical length requirements.
Versatile Protection: Choose from Polyimide or metal-based tubing based on your physical environment.

Core Applications

Our UHV fiber solutions are the trusted choice for high-tech research and infrastructure:

Particle Physics: Signal transmission in particle accelerators and beamlines.
Quantum Technology: Optical systems for quantum computers and quantum optics research.
Space Exploration: Light delivery for space simulation chambers and aerospace testing.
Analytical Science: Laser beam delivery for vacuum spectroscopy and chemical analysis.
