ANR51/LT/UHV - rotator (360° endless)

compact rotator with vertical rotation axis

The piezo driven rotator is designed for rotating small samples or up to two ANPx51 translation stages with high resolution in setups with 1" outer diameter.
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.
