ANPx321/RES/LT/HV - linear x-nanopositioner

bearing based linear nanopositioner for horizontal motion

The ANPx321 nanopositioner incorporates ceramic bearings to provide high stability positioning for applications under extreme conditions like cryogenic temperature, high magnetic fields, and vacuum conditions.
The positioner is designed for temperatures between 1K..373 K and pressures down to 1 E-8 mbar (/LT/HV).
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.
