XYZ Nanopositioning Stage from PI
Nanopositioning stage.
Auburn, MA, PI (Physik Instrumente) L.P. has added two new multi-axis stages for super-resolution microscopy applications, providing highly accurate motion with sub-nanometer resolution over travel ranges of 200µm in XY and XYZ.

The new PI nano1 x 3 series XY and XYZ nanopositioning stages are designed for inverted microscopes from the four major manufacturers: Leica, Nikon, Olympus and Zeiss. The low profile design of 20mm (0.8-in.) facilitates the integration. The large aperture accommodates microscopy accessories such as slide holders, Petri dish holders, etc. An optional 25 x 25mm positioning stage serves as a stable base for the piezo stage.

The 24-bit controller has USB, Ethernet, and RS-232 interfaces and analog control; 200µm XY or XYZ travel, closed-loop control for sub-nanometer precision. The stage is highly cost-effective because of its low-cost piezoresistive sensors; and it presents a very low profile of 20mm (0.8-in.) for easy integration.

With its 24-bit DAC converters, commanded resolution is improved by two orders of magnitude over the still widely used 16-bit converters. Despite the higher performance, cost was reduced. The controller is also compatible with all major image acquisition packages and comes with a wide variety of software drivers and programming examples.

For highly stable, closed-loop operation, piezoresistive sensors are applied directly to the moving structure of the stage and precisely measure the displacement of the platform. The very high sensitivity of these sensors provides optimum position stability and responsiveness as well as sub-nanometer resolution. The proprietary servo circuit significantly improves the motion linearity compared to conventional piezoresistive sensor controllers.
