ANRv220/RES/LT/HV - rotator (360° endless)

highest stability rotator with horizontal rotation axis providing

The ANRv220 rotator is designed for applications which require ultra low wobble. It is equipped with a special base plate for vertical mounting and allows rotating samples with a horizontal rotation axis.
The positioner is designed for temperatures between 1K..373 K and pressures down to 1 E-8 mbar (/LT/HV).
A combination of beryllium copper and titanium is the material used for this cryogenic nanopositioner, as it is nonmagnetic, and reliable low temperature performance.
