Several classes of XY-tables are now available:
- Air bearing XY tables provide the highest accuracy, performance and lifetime, since they contain no mechanical elements to wear. PI’s new A-322 PIglide Ultra version is based on an XY dual gantry design with liquid-cooled high-performance 3-phase linear motors and absolute linear encoder. This air bearing table can cover an XY linear motion travel range up to 500x1000mm with resolution to 1 nanometer.
- Integrated XY-tables with mechanical bearings and direct-drive motors. These 3-plate integrated XY-tables provide a lower profile compared to stacked XY-linear stages. While not as precise as an air bearing table, orthogonality of integrated 2-axis tables is typically an improvement over stacked XY-tables built from single-axis linear tables. For higher load and lower velocity applications, the integrated 2-axis stages are also available with ball-screw drives.
- Piezo-Flexure-Guided XY-Tables. 2-axis nanopositioning tables with piezo drives and flexure guides are often used in super-resolution microscopy, fiber-optic and semiconductor applications. Due to their high stiffness and low mass, piezoelectric XY-tables can provide high scanning frequencies while delivering sub-nanometer precise motion.
