Our hybrid vacuum feedthroughs integrate optical and electrical feedthroughs into a single CF, KF, ISO-K or fully custom flange. Optical feedthroughs can seal SM, MM, PM or POF fibers with either pigtail or adapter interfaces.

Complementary electrical feedthroughs include SUB-D, Micro-D, SMA or BNC providing versatile options for transmission of currents and electronic signals. 

Engineered for UHV service and a wide temperature range, these hybrid feedthroughs deliver helium leak rates down to 1×10⁻¹² mbar·L/s.

Advantages

  • Wide range of optical connector interfaces
  • SUB-D, Micro D, SMA, BNC and other electrical interfaces
  • Suitable for applications with SM, MM or PM fibers
  • Helium leak rate 10 -10 to 10 -12 [mbar.l/s]
  • The offered feedthroughs are compatible with UHV

Applications

  • Photonics – Laser and detector integration
  • Semiconductors – Signal and control in vacuum tools
  • UHV Research – Optical + electrical access for experiments
  • Aerospace – Thermal vacuum chamber interfaces
  • Medical R&D – Vacuum testing for diagnostic devices
  • Fiber Sensing – Optical sensors in vacuum environments
