- Introduction
- Controllers
- Feedback
P34 piezoelectric deflection platform is designed for large up to 80 mm in diameter. Their differential drive exhibits excellent angular positioning stability over a wide temperature range. P34's structure allows the top platform to perform high dynamic precision deflection motion on two orthogonal axes with common pivot points.

High Stability, Linearity and Dynamics
CoreMororow's piezo tip/tilt system is based on a parallel kinematic design. The internal four piezo actuators are paired differential controls that determine the platform deflection motion, which makes P34 piezo platform have excellent angular positioning stability in a wide temperature range. |
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.
