  Spinning Disk Super Resolution Imaging uses Piezo Control to Enhance Stability

Super resolution microscopy has the ability to produce biological images that show molecular level structures.

SDSI image of Histone 2B and Lamin ACAlthough the technique is limited when it comes to looking at live cells a number of research groups from around the world are working on overcoming these limitations, including a team led by Dr Ann Wheeler, Head of Imaging at the Queen Mary University of London’s Blizard Institute*, and Professor Martin Knight of Queen Mary’s School of Engineering and Materials Science. When Dr Wheeler, Prof Knight and their team needed improved stability for their new spinning disk super resolution imaging (SDSI) microscope, they turned to precision positioning specialists, PI Ltd for help...


  Precision XY Measuring Stage with Nanometer Resolution for Industrial Applications

The new MCS XY stage from PI miCos for industrial measurement technology combines high guiding and positioning accuracy with loads of up to 20 kg and high dynamics.

MCS XY Stage

Its areas of applications include industrial surface measurement technologies such as topology measurements on workpieces and optics or structural measurements on semiconductor wafers. Its high load capacity of 20 kg allows further axes to be mounted on the platform, such as vertical, rotary or tilting stages. The MCS system achieves its performance characteristics through selective combination of mechanical and electronic precision components....


  New Digital Controller from Physik Instrumente

Thanks to its high output power, the digital single-channel controller E-709.CHG from PI (Physik Instrumente) provides highly dynamic and nanometer-precise operation of piezo-based stages with high stiffness and electrical capacitance

pi_E-709.CHGThese positioning systems are mainly used in applications that require high throughput such as in microscopy. The digital technology contained within the controller increases its performance; digital control algorithms optimize the settling behavior and minimize linear deviation. Motion and servo-control parameters can easily be set with software commands...


  Focusing on nanopores with PI Dr Stefano Pagliara using the PI stage on an optical tweezers setupScientists at the University of Cambridge are using Physik Instrumente's P-517 3-axis precision nanopositioning system to further advance understanding of the action of molecules during transport through membrane nanopores. Dr Ulrich Keyser, Principle Investigator in the University's Cavendish Laboratory Biological and Soft Systems group, explained: "We are looking at the transport of single molecules through membranes made using silicon nanotechnology and glass capillaries or biological systems ­- lipid membranes with protein nanochannels."...


  PI Hexapods chosen for space mission Interferometer (Source: University of Glasgow)Scientists at the Institute for Gravitational Research, School of Physics and Astronomy, Glasgow University, have selected PI's M-824 Hexapod, a 6-axis micropositioning system, to construct space flight hardware for the LISA (Laser Interferometer Space Antenna) Pathfinder space mission, a major ESA-NASA initiative...


  PILine piezo motor technology for extra low-profile The M-660 PILine piezo motor rotation stage from Physik Instrumente (PI) offers a new dimension in rapid positioning, for applications including microscopy and mass storage solutions. The high speed U-164 PILine linear motors offer speeds of up to two rotations per second, with a maximum torque of up to 0.3 Nm.
