S-335 Piezo Tip/Tilt Platform

Beam Steering with Very Large Deflection Angles for Mirrors and Optics

Tip/tilt angle to 35 mrad, high optical deflection angle to 70 mrad (4°)
Resonant frequencies to 0.7 kHz (1" mirror) for dynamic motion and fast step-and-settle
Parallel-kinematic design: Two orthogonal tip/tilt axes with one common pivot point
Strain sensors for high linearity
Different versions available: Without mirror, ½" mirror, 1" mirror

S-335.2SH, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point. The general tolerance according to DIN ISO 2768-f-H applies to all nontolerated dimensions.

S-335.2SHM1, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point. The general tolerance according to DIN ISO 2768-f-H applies to all nontolerated dimensions.

S-335.2SHM2, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point. The general tolerance according to DIN ISO 2768-f-H applies to all nontolerated dimensions.

The patented 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.

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 are 100 % vacuum compatible and work in a wide temperature range.

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.

*** 2SHM2 version with mirror Ø 25.4 mm

The resolution of the system is limited only by the noise of the amplifier and the measuring technology because PI piezo nanopositioning systems are free of friction.

The specifications apply to 21 °C ±10 °C. The specifications can deviate outside of this range. If you have any questions, contact your PI representative.
