Our Approach Is Built on Precision, Stability & Absolute Process Control.
Optical fibers engineered for extreme vacuum, temperature & precision environments
High-vacuum environments demand materials that remain dimensionally stable, contamination-free, and optically reliable under extreme pressure and temperature conditions. Our specialty optical fibers are engineered specifically for applications where conventional polymer-coated fibers fail.
We manufacture metal-coated, spun, and custom optical fibers designed for ultra-low outgassing, high thermal tolerance, and long-term mechanical stability. These fibers are ideal for vacuum chambers, particle accelerators, semiconductor fabrication, synchrotron systems, and space simulation facilities.
By controlling every stage of production – from preform design to coating and final inspection – we ensure consistent optical performance, precise dimensional tolerances, and complete process traceability. Each fiber is produced to meet strict scientific and industrial requirements where failure is not an option.
High Vacuum Manufacturing – Precision Without Compromise
Modern high-vacuum systems require components that integrate seamlessly with automated, digitally controlled environments. Our manufacturing processes use real-time monitoring, inline inspection, and statistical quality control to guarantee fiber consistency and reproducibility across production runs.

Q&A
It is certainly possible to arrange a custom draw of low-birefringence fiber. In fact, most of our spun fibers are tailored to a specific device or aplication. Options include optimized beat length, specific wavelength cut-off, reduced cladding and polyimide coating.
Metal layers such as gold, nickel, or aluminum create a physical barrier that protects the glass fiber from exposure to corrosive fluids, solvents, hydrocarbons, and cleaning agents commonly found in oil & gas environments.
Metal coatings provide superior thermal stability, mechanical protection, and chemical resistance. They ensure accurate signal transmission in harsh industrial environments where polymer coatings fail.
