MultiBase - XY Stages

The MultiBase stages provide modular platforms for the manipulation of components in the X and Y planes. A MultiBase may be used as a discrete stand-alone stage or combined with our range of Linear Shift Mechanisms and MagiDrives to build an entire six-axis manipulator.  The MultiBase XY stage provides the platform for UHV Design's  MultiStage XYZ manipulator range along with the MultiCentre manipulators supplied complete with sample processing capabilities.

The MultiBase design includes two parallel flanges. One remains fixed, whilst the other provides the movement. A high quality, supple, edge welded bellows spans the flanges to accommodate the required motion while ensuring an all-metal vacuum enclosure. The device works by adjusting the position of the travelling flange in relation to the fixed system-mounting flange. Positioning of the travelling flange is controlled through two external leadscrews (one for each axis of movement) removing the need for 'cross roller slides'.  A kinematic guide mechanism ensures smooth and precise motion.  The MultiBase is fitted with a unique anti-backlash system, resulting in an extremely accurate and repeatable mechanism.

Travel Definition

MultiBase movement may be defined as the maximum X or Y travel, for each axis, which equates to the vector. Alternatively the travel may be expressed as the maximum combined X and Y offset to achieve the vector as illustrated to the left using the XY100/64 as an example.
