Merge Nanopositioning Stages to Multi-Dimensional Systems
The modular concept of attocube positioners in combination with a consequent use of similar mounting patterns enables the assembly of multi- axis positioning units composed of( several) different types of nanopositioning stages. By merging several positioning units with distinct travel ranges and motion options, motor assemblies with up to six degrees of freedom can be built.
Cross mounting rules
Following general rules apply for building multi-dimensional setups:
• a positioner with a lower number should not be used to support one with a larger number, e. g. an ANPx51 should not carry an ANPz101.
For the standard ANPxyz-configuration, two x-positioners( one rotated by 90 °) are mounted on top of a z-positioner.
• cross-mounting between two different sized models( e. g. a 51 series positioner on top of a 101 positioner) may require an adapter plate( see adapter plates overview in accessories section on our webpage).
• all bearing-based positioners( ANPx3 * 1 series) can be mounted on a L-bracket which enables vertical positioning.

Combining Goniometers
Each size of goniometer is available in two versions which are usually used as a pair for theta( Θ) and phi( Φ) motion. The Θ positioner mounted on top of the Φ positioner forms a tip-tilt stage with a common center of rotation. Mounting is done directly with two or four screws.
Combinations with other positioners are explained above or in the accessories sections on our webpage.
