15 May 2006 Physik Instrumente (PI), a leading producer of nanopositioning systems have introduced a new high-speed nano-focusing system. High speed Z-axis image acquisition is a prerequisite for the generation of 3-D views of bio-samples in high resolution optical microscopes. Conventional Z-axis drives use motorised actuators to create numerous focus planes during the focusing procedure. The individual slices are then processed using special software to create one 3-D image. Using piezo actuated vertical motion with PIs new controller, focusing speeds are increased by up to 10 x. Resolution of 1nm is achievable, approaching 100 times that of motorised systems. The result of these improvements is higher quality images in much less time.
PIs affordable E-625 nanopositioning controller produces movement and settling times of only 10mSec. The system boasts both a high bandwidth analogue interface and a 20-bit digital interface for maximum flexibility. It integrates a low-noise piezo amplifier, a high speed servo controller and sensor electronics for absolute measurement nanopositioning sensors.
Other applications of the E-625 controller will be found in scanning and alignment tasks in microscopy, biotechnology, optics, semiconductor technology and photonics packaging.
