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..

Light and compact, the P-604 from PI is a PiezoMove Linear Actuator. Ideal for OEM applications in optics, medical technology, biotechnology, and microfluidics, this product is inexpensive and features a 300µm travel range.

PI's PiezoMove High-Stiffness Linear Piezo Actuator features flexure guides for linear motion with minimal tip and tilt. P-602 is available with integrated position sensors and is an ideal OEM actuator for force generation in adaptive systems technology.

The H-811.I2V hexapod from PI features a parallel-kinematic design for six degrees of freedom making it significantly more compact and stiff than serial-kinematic systems, higher dynamic range, no moved cables. Additionally, this promotes higher reliability, and reduced friction, and is suitable for vacuum environments to 10-6 hPa.

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 demo shows a closed-loop XY-table in high speed scan and alignment. These V-508 linear translation stages are run run by an ACS industrial motion controller with intelligent alignment algorithms.

  • The pivot point demo shows the advantages of a programmable pivot point in hexapod parallel kinematics active alignment systems. The PI H-811 Hexapod 6-axis motion system and P-616 piezo nano-scanner are mounted on a Cascade Microtech wafer prober.

  • PI's Hexapod 6DOF Parallel Motion platforms have a very useful feature for active alignment and optimization applications - a user programmable pivot point. A high performance hexapod motion controller handles all the necessary coordinate transformations, very easy for the user.

  • Shannon from Mad City Labs takes you through the company's product line of nanopositioning systems. Learn about nanopositioners and their key attributes with this informative video.

  • 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.
