S-331.2SH
High dynamic tip-tilt platform with high stiffness, 3 mrad tip/tilt angle, strain gauge sensor, D-sub 37 connector (m)
S-331 High-Speed Tip/Tilt Platform
Short Settling Time and High Dynamic Linearity
- Tip/tilt angle up to 5 mrad, optical deflection angle up to 10 mrad (0.57°)
- High resonant frequencies to 10 kHz(0.5" mirror) for dynamic motion and fast step-and-settle
- Parallel-kinematic design for identically high performance characteristics for both tip/tilt axes
- Position sensors for high linearity
- For mirrors up to Ø 12.7 mm (0.5")
Unidirectional linearity error for both axes: The solid blue line represents axis 1, the dotted brown line represents axis 2. The linearity error at full displacement of the S-331.5SH with the E-727.3SD digital piezo controller is less than 0.05 %.

Outstanding lifetime due to PICMA® piezo actuators
The PICMA® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA® actuators offer an up to ten times longer lifetime than conventional polymer-insulated actuators. 100 billion cycles without a single failure are proven.
High guiding accuracy due to zero-play flexure guides
Flexure guides are free of maintenance, friction, and wear, and do not require lubrication. Their stiffness allows high load capacity and they are insensitive to shock and vibration. They work in a wide temperature range.
High dynamics multi-axis operation due to parallel kinematics
In a parallel-kinematic multi-axis system, all actuators act on a common platform. The minimum mass inertia and the identical design of all axes allow fast, dynamic, and nevertheless precision motion.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
