PI (Physik Instrumente) L.P. Compact Piezo Tip/Tilt Platform S-335

The S-335 is a piezo tip/tilt platform for precision beam steering with up to 35 mrad deflection per axis. It uses a parallel-kinematic design with flexure guides for zero-play motion and a common pivot point. Integrated strain gauge sensors enable 1 µrad system resolution and 1 µrad repeatability. PICMA® piezo actuators ensure long-term reliability with proven 100 billion cycle lifetimes. Variants include models without a mirror, with a 12.5 mm mirror, or with a 25.4 mm mirror. Resonant frequencies range from 0.7 kHz with a 1-inch mirror to 2 kHz unloaded. The titanium body and aluminum housing operate from -20 to 80 °C, with a 37-pole D-sub connector and 2 m cable. All variants share identical core performance specs including 0.05% linearity and 6.2 µF capacitance per axis.
