ANRv51/CuBe/RES+/ULT/HV - Rotator (360° endless)

compact rotator with horizontal rotation axis

This ANRv51 series rotator is equipped with a special base plate for vertical mounting. It enables to sample rotation with a horizontal rotation axis with high resolution, and is designed to fit in 1" diameter setups.
The positioner is designed for temperatures between mK..373 K and pressures down to 1 E-8 mbar.
For ultra low temperatures in the mK range, a body of beryllium copper is optimal for measurements that are sensitive to small magnetic fields, as titanium can superconduct and expel magentic flux to change the sample environment.
