ANPz51/LT/UHV - linear 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 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.
