PI (Physik Instrumente) LP has introduced the E-712 digital piezo stage controller for nanopositioning systems with up to six axes. It features a sensor update rate of up to 50 kHz, stable 20-bit digital-to-analog converters, a 600-MHz processor and an Ethernet interface for remote control via the Internet. Other interfaces include USB, RS-232 and high-bandwidth analog. Digital linearization algorithms based on higher-order polynomials improve the positioning accuracy to 99.999% of the travel range, and dynamic digital linearization eliminates tracking errors in scanning applications.
