AUBURN, Mass., Dec. 28, 2007 -- PI (Physik Instrumente) L.P. said it has extended the S-330 high-dynamics piezo tip/tilt platform line by several new large-angle models.
The new additions to the S-330 piezo steering mirror platform series provide for larger deflection angles, yet retain the excellent dynamic properties of the original design, the company said. The systems are fast and compact tip/tilt units, providing precise angular motion of the top platform around two orthogonal axes. These flexure-guided, piezoelectric platforms can provide higher accelerations than other actuators, enabling step response times in the submillisecond range. Closed-loop and open-loop versions with three different tilt ranges up to 10 mrad (20 mrad optical deflection) are available.
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. The single pivot-point design also prevents the drawback of polarization rotation, which is common with stacked systems, e.g. galvo scanners, the company said.
Typical applications for these mirror platforms include: Beam correction, laser surgery, image stabilization, interlacing, dithering, laser scanning/beam steering, optical communications and high-resolution microscopy/spectroscopy.
