PI’s High-Precision Drives
This video shows the High-Precision Drives from Physik Instrumente (PI). Refractive eye surgery requires rapid and high-precision laser beam steering systems. Piezo-based, two-axis tilting platforms allow for large deflection angles, compact size, and nanometer resolution. The parallel kinematic design (all piezo actuators act on the moving platform) results in the same performance such as dynamics and accuracy and the same point of rotation for both tilting axes.
