Something new in microscopy: 1mm objective stage with piezo stepping drives
 |
Piezo stepping drives from Physik Instrumente (PI) can be combined with a high-resolution linear encoder for nanometer accuracy over the complete scanning range - and are now also available for PIFOC focusing systems for microscope objectives.
The N-725 PIFOC scanner for microscope objectives with Nexact piezo stepping drives provides travel ranges of up to one millimeter along the optical axis. At the same time the technology allows rapid positioning: The N-725 focusing system achieves transient times of around 20 milliseconds for steps of 200 nanometers. It has an extremely compact design and is no larger than conventional, piezo-based PIFOC objective stages.
The focal plane can easily be changed with a single mechanism thanks to the combination of high resolution and long travel ranges.
Nexact piezo stepping drives combines high resolution, high force and high speed
