Press release from: PI (Physik Instrumente) L.P. Piezo Nano Positioning

PI nano piezo stage with piezo controller and optional M-545 manual XY microscope stage.

PI nano piezo stage with piezo controller and optional M-545 manual XY microscope stage.

Super resolution microscopy (nanoscopy) refers to optical techniques that go beyond the diffraction limit. They are often used as tools for bio-medical research revealing deatails of proteins and biomolecules, resolving to the 10 nanometer scale. Most super-resolution microscopes incorporate piezo precision positioning devices for scanning or focusing.

The new PI-nano™ series piezo stages feature a low profile of 20 mm, large aperture & deliver highly accurate motion with sub-nanometer resolution in 2 & 3 axes. A piezo controller is included; it has a 24-bit USB port, Ethernet, RS-232 & analog interface, + solid software support for all major image acquisition packages.

The piezo stage is supplemented by the optional M-545 manual XY microscope stage available in different versions for Olympus, Nikon, Zeiss and Leica microscopes.

Reduced Cost through Optimization for the Application
The PI nano™ series of piezo stages extends PI’s successful P-527, P-733 and P-563 series of capacitive direct-metrology nanopositioning stages. PI nano™ series systems were developed to provide high performance at lower cost, by adapting mechanics and controller exactly to the requirements of the target applications.

Improved Linearity with Special Controller
For highly stable, closed loop operation, piezoresistive sensors are applied directly to the moving structure and precisely measure the displacement of the stage platform. The very high sensitivity of these sensors provides optimum position stability and responsiveness as well as sub-nanometer resolution. The proprietary servo controller significantly improves the motion linearity compared to conventional piezoresistive sensor controllers.

Application Examples
Scanning Microscopy, Single Molecule Microscopy, 3D Imaging, Autofocusing, Scanning and Alignment Tasks in Bio-Nanotechnology.
