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.
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
