What Is The Difference between Parallel Positioners And Stacked Serial Kinematics?
When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play.  Continue Reading..

The directly driven flat rotation stages of the PIglide RLA series are designed for the highest precision. They have a low profile and a large clear aperture. The RLA stages offer a superior travel accuracy, flatness, and wobble performance.

The E-709.1C1L from PI is best suitable for piezo-based single-axis nanopositioning systems with capacitive sensors. The output voltage is -30 to 130 V and it features an amplifier and sensor evaluation, optimized for dynamic applications. 

The E-413 amplifier can control a piezo tube in two or three directions of motion. The possible directions of motion of a piezo tube depend on the number of its electrode segments.

The V-308 from PI is a high-dynamics positioner used for microscope objectives, featuring a voice coil PIFOC focus drive. This positioner was created with an integrated weight force compensation, PIMag® voice coil motor, a crossed roller guide, and provides direct position measuring.

The DPT-E range of actuators by Prior Scientific are designed with capacitive feedback control to give precise positioning, accuracy, and speed.

The NanoScan OP400 from Prior Scientific is a nanopositioning Piezo objective scanner. There are many applications for this product including optical sectioning producing 3D images, autofocus systems for time lapse imaging, high content screening, surface analysis, wafer inspection, and scanning interferometry. 

Prior Scientific's NanoScan-SP range of Piezo driven stages are compatible with the Prior motorized stage as well as many common microscopes when using appropriate adapter plates. Applications for this series include live cell imaging, surface analysis, water inspection, and more.

The A-523 by PI is an air bearing Z tip/tilt stage with direct drive. The Z tip/tilt stage is ideally suited for high-precision applications including wafer inspection, fiber positioning, optics positioning, flat screen inspection, maskless lithography, and ultra-LED manufacturing.



  • Motorized Gantry Stages with Direct Drive motors provide higher speed, performance and precision compared to belt-driven gantries or screw driven gantry stages.

  • High speed and high precision gantry stages and XYZ motion stages provide the basis for industrial highly accurate laser machining and 3D printing processes. Fast linear motors provide frictionless motion with zero wear, in contrast to screw and belt driven gantries and stages. Non-contact linear motors not only provide higher speed and precision but also increased reliability.

  • PI's Next Generation objective nano-positioners for microscopy and surface metrology provide higher speed, precision and longer travel ranges up to 800µm, along with easier integration. Applications for nano-focusing stages include multiphoton fluorescence microscopy, optical coherence tomography, wafer surface inspection and laser materials processing.

  • The A-688 Direct-Drive Air Bearing Rotation Table is motorized with a 3-phase high performance direct-drive torque motor. It is guided by air bearings and provides a large aperture - ideal for transmitted light test and metrology applications.

  • High performance piezoelectric transducers were sent to the Mars after testing their reliability for 100 Billion cycles. The help to find out if there once was life on Mars.

  • Piezolelectric sound transducers can be used for wireless downhole communication, sonar applications, and long distance underwater communication up to several kilometers.  PI’s piezo transducer division specializes in the design and manufacture of standard and custom piezoelectric transducers for industrial, medical and research applications.

  • Ultrasound can be used for industrial inspection and automation - the technology is similar to the one know from medical ultrasonic imaging. Piezoelectric ultrasonic transducers also find applications in non-contact distance measuring, structural health monitoring, object recognition and measuring instruments for volume, filling level, distance and acceleration.
