ANPz51/CuBe/RES+/ULT/HV - Linearer z-Nanopositioner

compact linear nanopositioner for vertical motion

The compact ANPz51 provides high resolution nanopositioning to fit 1" diameter setups. For a full 3D motion stack, two ANPx51 can be combined with an ANPz51.
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.
