Team on 19 December 2007
Piezo mirrors provide larger angles and
bandwidth
These flexure-guided, piezoelectrically driven systems can provide higher accelerations than other actuators, enabling step response times in the sub-millisecond range
PI (Physik Instrumente) extends the S-330 high-dynamics piezo tip/tilt platform family by several new large-angle models Typical applications include beam correction, laser surgery, image stabilisation, interlacing, dithering, laser scanning / beam steering, optical communications, high resolution microscopy/spectroscopy two-axis, flexure guided, no polarization rotation

Phase shifters for interferometry and spectroscopy
High-speed phase shifters are compact and extremely responsive systems offering angstrom level resolution with piston movement up to 2um with sub-msec response and settling dynamics
S-330 steering mirror platforms provide precise angular tip/tilt motion of the top platform around two orthogonal axes.
The single pivot-point design also prevents the drawback of polarisation rotation, which is common with conventional two-axis stacked systems, eg, galvo scanners.
Closed-loop and open-loop versions with three different tilt ranges up to 10mrad (20mrad optical deflection) are available.
Parallel-kinematics: smaller with improved stability, linearity and dynamics.
PI piezo steering mirrors are based on a parallel-kinematics design with coplanar rotational axes and a single moving platform driven by two pairs of differential actuators.
The advantage is jitter-free, multi-axis motion with excellent temperature stability.
Compared to stacked (two-stage), mirror scanners, the parallel-kinematics design provides symmetrical dynamic performance in both axes with faster response and better linearity in a smaller package. Request a free brochure from PI (Physik Instrumente) ...
