High Performance Motion Control – Systems Approach Provides Nanometer Precision for Industrial Applications

High performance motion control plays a key part in positioning and handling applications, such as those in semiconductor manufacturing, laser and materials processing, optical inspection systems, additive manufacturing or industrial digital printing. In addition to providing reliability and robustness, deterministic behavior with minimized latency, high-speed synchronization with external devices, such as lasers and cameras, is […]

Tracking Down Nanometer Instabilities: Every Detail Matters

When you work with nanometer resolution motion equipment, details matter. Instabilities can be caused by a variety of things, ranging from floor disturbances leaking past isolation systems, to acoustic energy coupled into the application structure, to tuning issues with the motion system embedded in the application, to resonant excitation of structural elements of the setup. In real life applications, instabilities […]

“Micropositioning” – Classical Precision Positioning Technologies still Going Strong

Striking the right balance between affordability, accuracy, and reliability Traditional linear and rotary “micropositioning” stages are based on servo and stepper motor-driven leadcrews and ballscrews and mechanical bearings. They are classical components for precision motion control applications, spanning from lab-automation to industrial assembly and inspection. “Micropositioning” got its name from precision levels in the micrometer […]

Nanopositioning Metrology, Gödel, and Bootstraps

Why External Metrology Matters in Nanopositioning More than 80 years ago, a discovery by Austrian Kurt Gödel put an end to the dream mathematicians had pursued for centuries: a final unifying “Theory of Everything” or the idea that a system could be devised strong enough to verify itself. Gödel’s findings may seem rather obvious, but […]

From IoT to IoP – the Internet of Smart Piezos

A discussion with leading piezo experts on ceramics, nanopositioning, intelligent piezo systems, and weather stations Q&A with Dr. Harry Marth, Head of Piezo Technology Innovation, and Dr. Mathias Bach, Head of Piezo Systems at Physik Instrumente (PI), Karlsruhe, Germany. Most people would be looking forward to retirement after a successful career of 45 years. But […]

Advances in Laser Micromachining and Microprocessing

New Motion Control Approaches Deliver Improved Accuracy and Faster Time to Market Introduction Experienced Laser Microprocessing and Micromachining system integrators have no trouble providing proof of concept demonstrations for new applications. Turning the concept into a robust solution is a different story altogether – at least it used to be.  Here is why: Delivering laser […]

Piezo Flexure Stages and Piezo Shear Actuators in Ion Conductance Microscopy

In contrast to Super-Resolution Optical Microscopy, scanning ion conductance microscopy (SICM) does not require precision optics, instead an electrical probe tip is scanned.  Like optical microscopy, SICM is also used for studying live cells and, for example, the interaction of nanoparticles with the cell membrane. In the recently published article, “A Low-Cost, Large Field-of-View Scanning […]

Hexapod Robots in Laser Microsurgery Research

Laser micro-surgery can benefit from tracking and image-based methods that improve precision and safety. Advanced software together with stereo camera feedback allow for motion estimation reduce tracking errors.  A highly precise parallel kinematics motion system (Model H-824 from Physik Instrumente) with 6 degrees of freedom was used to evaluate the performance. More information is available […]

XYZ Positioning Mechanism Integrated in Automated Medical Instrument Developed in Partnership with ITL

Standard or Custom Engineered Solutions when Time is Critical? The old question – standard or custom – was one of the key considerations when ITL Group decided on what precision multi-axis motion system to use in one of their latest projects. In this particular case, ITL was approached by a client with an open frame […]

History and Future of Photonics Alignment Automation, Test & Assembly of SiP Components

From Electronics to Photonics The first computer link using optical fibers was commissioned four decades ago to safeguard communications from electromagnetic interference at the Cheyenne Mountain strategic command center [1]. Since then we have seen broad adoption of photonic communications technologies in an unfolding pattern of consistently diminishing physical scale: As a replacement for costly […]
