Compact vacuum feedthrough

PTB-News 1.2015
Especially interesting for
  • manufacturers of vacuum components
  • process control engineering

How can highly sensitive optical fibres be introduced into vacuum vessels so that they can be rotated in the narrowest of spaces and displaced longitudinally? A new development by PTB helps solve this problem. It enables optical fibres to be positioned and subsequently adjusted. Hereby, leakages, which may occur in conventional designs, are minimized, the risk of cracking is reduced due to a compressionfree holder with integrated strain relief, and the shearing and torsion strains are prevented so that optimum reusability is possible. (Technology offer #373)

  • the fibres can be rotated and longitudinally displaced
  • compression-free integrated strain- and torsion relief
  • reusable
  • leakage rate < 5 × 10–10 Pa L/s
