- Introduction
- Controllers
- Feedback
P31 piezo tip/tilt platform can offer a beam deflection angle of 50 mrad. This deflection system is based on a proven parallel kinematics design with two axes of motion being perpendicular coplanar axes with common fixed points, featuring high resolution, high Positioning accuracy and so on.

High Stability Linearity Dynamics
P31 is equipped with high-reliability piezo actuators with preloaded force that are integrated into a mature hinge guidance system that has been analyzed by FEA. The piezo actuators are stacked co-fired piezoelectric ceramics that provide better stability and reliability. |
Driving Principle Piezo Tip/Tilt Platform(2-axis motion) is based on parallel kinematic design with coplanar axis and moving platform. 4 piezo actuators are placed at a 90° angle interval, paired differential control distribution. 2 pairs of differentially driven actuators provide the highest achievable angular stability over a wide temperature range. Its tilt motion is achieved by two pairs of piezo actuators in a push-pull motion, controlled by a bridge connection circuit.
