Physik Instrumente Introduces PI Nano Z Nanopositioning Stages

Published on January 22, 2010 at 5:32 AM

The new PI nano™ Z low-profile piezo Z stages are optimized for very fast step and settle and easy integration into high-resolution microscope applications. They feature a very low profile of 0.8" (20 mm), a large aperture, and travel ranges of up to 200 µm with sub-nanometer closed-loop resolution-ideal for leading-edge microscopy and imaging applications.

PI nano™ Z nanopositioning stages (shown with optional slide and Petri dish holder) feature a very low profile of 20 mm (0.8”), a large aperture and deliver highly accurate motion with sub-nanometer resolution.

Cost Effective Design, High Performance

PInano® series piezo positioning stages are designed to provide high performance at minimum cost. 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.

Features & Advantages

  • Extremely Fast Step & Settle, From 5 msec
  • Low Profile for Easy Integration: 20 mm (0.8")
  • 100 and 200 µm Travel Ranges
  • Longest Lifetime with Proprietary PICMA® Piezo Technology
  • Cost Effective due to Low-Cost Piezoresistive Sensors
  • Compatible w/ Leading Image Acquisition Software Packages
  • Closed-Loop Control for High Repeatability and Accuracy
  • 24 Bit USB Controller & Software Included

Working Principle / Reliability

Flexures optimized with Finite Element Analysis (FEA) are employed to guide the PInano® series stages. FEA techniques give the design the highest possible stiffness in, and perpendicular to, the direction of motion, and to minimize linear and angular runout. Flexures allow extremely high-precision motion, no matter how minute, as they are completely free of play and friction. The award-winning PICMA® piezo drives are more robust than conventional piezo actuators, featuring superior lifetime and performance in both dynamic and static applications. Because guidance, actuators and sensors are all maintenance-free, these nanopositioning systems achieve outstanding levels of reliability.

Controller & Software Included

The PInano™ Z stage comes complete with a powerful closed-loop controller.
