12 Dec 2007 Physik Instrumente (PI), a leading manufacturer of nanopositioning products has introduced the E-761, the world s first PCI-Bus nanopositioning controller. The new PI instrument is designed to give more flexibility and better overall value that any other digital piezo controller currently available.
Many of today s high-tech applications in imaging, metrology, scanning microscopy and surface analysis require a combination of high-speed motion control coupled with high resolution. They also need extremely fast data acquisition and precise synchronisation between the imaging and motion control devices. Peripheral components with PCI-Bus interfaces re ideally equipped to satisfy these demands because the PCI-Bus was designed to give high bandwidth access to the microprocessor in the PC. The all-new PI product is the first commercially available fully digital piezo nanopositioning controller on a PCI board. The technology allows fast communications and easy integration with devices such as frame grabbers a major benefit in real-time data acquisition or when operating multiple controllers simultaneously.
Features of the new PI controller include closed-loop control of three axes using capacitive position feedback, four on-board piezo drivers eliminating the need for external amplifiers and co-ordinate transformation for active trajectory control. A powerful 32-Bit DSP and 24-Bit D/A converter offer sub-nm position accuracy and a high bandwidth analogue command interface accommodates analogue position data systems and supports external triggering tasks. Digital linearisation is provided for improved accuracy and Plug & Play auto-calibration allows for interchangeability of positioning systems. The controller comes with a large variety of software tools, LabView drivers and Windows® DLLs for easy setup, system optimisation and integration in application specific programmes.
