Ocean Insight offers vacuum feedthrough (VFT) accessories for vacuum chamber applications such as semiconductor processing. VFTs include general-purpose bolt-style feedthroughs with an O-ring, and feedthroughs mounted in conflat and ISO KF industrial-grade flanges. All have in-vacuum and in-air side male SMA 905 connectors for coupling to optical fibers.


  • Multiple options -- bolt-style feedthroughs with O-ring and conflat and industrial-grade flanges
  • O-ring style  -- useful for NEMA enclosures, glove boxes and moderate- to high-pressure applications
  • Flange style -- conflact and ISO KF options for mounting to an existing vacuum chamber port
  • UV-Visible version -- designed for use with UV-Visible fibers (300-1100 nm)
