Vacuum Pigtailed Fiber Optic Feedthroughs

SQS fiber optic feedthroughs ensure vacuum compatibility by sealing SM, MM, and PM fibers into standard (CF, KF, ISO) or custom flanges, typically made from 304L or 316L stainless steel. Fibers can be sealed individually or in groups for multi-channel applications.

Protective tubing options include PTFE, PEEK, or stainless steel for mechanical and environmental protection. Sealed fibers can be terminated with UHV-compatible connectors (FC/APC, FC/PC, ST/PC, SMA905) or integrated into V-groove arrays, matrix arrays, or fiber collimators.

The atmospheric side supports additional connector options, including LC, E2000, SC, MTP, and MMC.

Advantages

• Wide range of connector interfaces for both vacuum and atmospheric sides
• Compatible with SM, MM, POF and PM optical fibers
• Standard and custom flange solutions (CF, KF, ISO, or custom designs)
• Multiple protective tubing options (PTFE, PEEK, stainless steel)
• UHV-compatible design for high and ultra-high vacuum applications
• Multi-channel configurations with individual or grouped fiber sealing
• Integration with other feedthroughs (electrical or optical) in a single flange
• High mechanical stability and durability with precision-machined stainless steel flanges

Applications

• High and ultra-high vacuum systems – research and industrial use
• Fusion and particle accelerators – optical interfaces in extreme conditions
• Laser systems – optical signal transmission in vacuum
• Semiconductor and photonics – vacuum chamber applications
• Aerospace and defense – optical data transfer in space simulations
• Spectroscopy and sensing – controlled vacuum environments
• Medical and biotech equipment – vacuum-compatible optical connections
