What is the Difference between a Piezo Actuator and a Programmable Piezo Shim?

New Tools for Design Engineers of Optics and Precision Mechanical Systems Piezo stack actuators have been used in applications such as photonics alignment, positioning, force generation, and fast valve actuation for several decades. They provide high dynamics, but can also be used for quasi-static applications due to their high-stiffness and stability. The principle is relatively […]

Hexapod 6-Axis Micro-Robots – Enablers for Today’s Advanced Camera Manufacturing… and Tomorrow’s

Hexapod micro-motion robots are a novel motion technology that provides all six degrees of freedom in an unusually stiff, compact, and high-precision structure, composed of a single moving platform supported in parallel by six motorized struts arranged with optimized constraint (“parallel kinematics”). From a motion control standpoint, hexapods are the equivalent of an XYZ stack with […]
