CTU is a low range, high resolution translation unit for use at cryogenic temperature.

Its main features are as follows:

  • Range ±1 mm
  • Load >30 N
  • Speed 0.01-0.5 mm/s
  • Operating Temp 12-300K
  • Resolution <50 nm
  • Mass 1.32 kg
  • Size 208x177x39mm

The unit is a multipurpose device capable of fine open or closed loop positioning.

This device can be used as an active element in infrared instrumentation for compensating thermo-elastic deformation, moving optical elements or sensors.


CTU motion system is based in thin flexure deformations to assure repeatability, and for closed loop applications it incorporates a non-contact capacitive sensor.
