ANR101/RES/LT/UHV - rotator (360° endless)

rotator with vertical rotation axis

This rotator enables precise rotation of samples around 360° endless in both directions. It includes a 2 mm aperture for routing wiring to the sample.
The positioner is designed for temperatures between 1K..423 K and pressures down to 5 E-11 mbar (/LT/UHV).
Titanium is the material of choice for our cryogenic nanopositioners, as it is light, nonmagnetic, and has a coefficient of expansion matching the piezo and other elements of the drive for reliable low temperature performance.
