Vacuum Fiber Optic Feedthroughs

Engineered for ultra-high vacuum and positive pressure environments, our fiber optic feedthroughs are fully customizable—select your adapter interface, sealed fiber type (SM, MM, or PM), flange design, and sealing method to meet your application needs. Built with a robust steel housing and a hermetically sealed fiber, they feature adapter interfaces for FC, SMA 905, and ST connectors.

Designed for rigorous conditions, these feedthroughs offer helium leak rates of 10⁻¹⁰ to 10⁻¹² mbar·l/s and include serviceable components, such as replaceable ceramic mating sleeves and adapter interfaces.

Available as standalone units or integrated into flanges (FC, KF, ISO, or custom configurations), they can be welded or sealed with a Viton O-ring— with O-ring sealed models engineered for easy removal from the flange if needed.
