Applications for Vacuum Passthru:

  • in high electrical fields
  • in high magnetic fields
  • at high temperatures
  • at cryogenic temperatures
  • in cryogenic fluids
  • in ultra high vacuum

Vacuum Passthru Hardware

Fiberoptic Displacement Sensors are ideal for displacement and position measurements in vacuum. They have a wide temperature range, are UV compatible, small in size and can have sub-micron accuracy.

Philtec vacuum passthru hardware enables installation of fiberoptic probes into vacuum chambers over a wide variety of applications.
