Auburn, Mass. – The nano1x3 ™ series X-Y and X-Y-Z nanopositioning stages from PI (Physik Instrumente) are multi-axis stages for super-resolution microscopy applications, providing highly accurate motion with closed-loop control for sub-nanometer precision over travel ranges of 200µm in X-Y and X-Y-Z planes.
The stages feature a piezo controller and comes with three, 24-bit digital interfaces (USB, TCP/IP, and RS-232) and a wide-band analog interface for compatibility with all control signals. With 24-bit DAC converters, commanded resolution is improved by two orders of magnitude over the still widely used 16-bit converters. 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.
