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 .
