ANPz51eXT/RT - linear z-nanopositioner

compact linear nanopositioner for vertical motion with extended range

The compact ANPz51eXT provides high resolution nanopositioning to fit 1" diameter setups over an extended travel range. For a full 3D motion stack, two ANPx51 can be combined with an ANPz51eXT.
The positioner is designed for ambient conditions (/RT).
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.
