This fast direct-drive 2D Piezo Steering Mirror Mount (2D laser steering mirror) provides a larger diameter than the S-330 laser mirror. It can handle optics to 3” diameter (75mm) and also uses a differential tip-tilt drive for high-velocity motion with fast step and settle and sub-microradian resolution. S-340 can provide 2D mechanical angles to 2 mrad with optical deflection angles to 4 mrad. Closed Loop control with feedback sensors provides excellent repeatability and accuracy!

Applications of this fast active optic 2-axis mirror mount are beam switching, beam dithering, laser beam control, laser cavity stabilization, image dithering and stabilization, optical canning, and cavity tuning. The S-340 2-axis tip/tilt platform can be equipped with gratings, optics and mirrors. The differential direct drive piezo stack actuators provide higher stiffness and faster response than amplified piezo actuators based on lever arm transmission. Due to the higher stiffness, the S-340 can provide higher bandwidth. For ultra-long lifetime the PI piezo mirror mounts are equipped PICMA® low-voltage piezo stacks that are ceramic encapsulated and have shown 100 billion cycles in testing for the Mars rover Space mission.

Computer Control, Programming, Software:

The fine steering mirrors can be computer controlled via a digital nanopositioning motion controller such as the E-727 multi-axis controller series. LabView drivers and MatLab examples are available for easy integration.

If Z motion is required, other PI focusing drives and phase shifters are available. 2-axis laser steering mirrors with larger angles are available with direct-drive voice-coil motors, as part number V-931.

What is a Fast Fine Steering Mirror?

Fast fine steering mirror systems are used to direct light, or stabilize light, mostly laser beams. They can also directly stabilize an imaging sensor thus providing higher resolution, another way of operating them is in pixel shift mode, where sub-pixel resolution can be achieved which is important with high end sensors. Fast steering mirrors can be designed for rotation around 1 degree of freedom (tilt-axis) or in two-axis designs (2D mirror mounts). 3-Axis designs also provide piston mode (Z-motion) which can be useful for phase shifting and waveform correction.

Why Piezo Mirror Mounts?

Piezo actuators are very stiff, solid state motors that can provide faster reactions to an input signal than other types of motors, achieving rotation with very high-bandwidth in these mirror mounts, along with extremely high accuracy and sub-microradian resolution. Piezo steering mirror mounts can be designed in very compact OEM packages in a very rugged design, to be vacuum and space compatible. Most commercial applications are found in laser beam control, optical stabilization, laser tracking, laser pointing, image dithering and stabilization. Piezo elements do not generate magnetic fields and are not influenced by them and tests at Fermi National Lab with PI PICMA® actuators have been conducted up to 5*10^8 Rad.

This fast 2D piezo mirror mount is ideal for laser beam control and fast steering applications. It’s long travel range (angular tip/tilt range) is made possible with the use of amplified piezo actuators, operated in differential push pull mode. Closed Loop control with feedback sensors provides excellent repeatability and accuracy! The S-335 2D Piezo Mirror Mount can provide 35mrad of mechanical angular deflection in 2 axes, and 70mrad optical deflection. For ultra-long lifetime the PI piezo mirror mounts are equipped PICMA® low-voltage piezo stacks that are ceramic encapsulated and have shown 100 billion cycles in testing for the Mars rover Space mission.

Short Settling Time, High Dynamics and Linearity

Tip/tilt angle to 35 mrad, high optical deflection angle to 70 mrad (4°)
High resonant frequencies for dynamic motion and fast step-and-settle
Parallel-kinematic design: Two orthogonal tip/tilt axes with one common center of rotation
Strain sensors for high linearity
Different versions available: Without mirror, 1/2" mirror, 1" mirror

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

Outstanding lifetime thanks to PICMA® piezo actuators
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.

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.
