Piezo beam steering mirrors for precision optic applications
Physik Instrumente’s (PI) S-331 fast tip/tip platform is a piezo steering mirror that is designed for milli-second response and settling time and dynamic linearity. They are designed for precision optics applications in ambient and vacuum environments. The S-331 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 polarization rotation, which is common with conventional 2-axis stacked systems such as galvo scanners. The steering mirrors are powered by 100% ceramic insultated actuators that have a long lifetime, and are not sensitive to humidity or high operating temperatures. The steering mirrors’ temperature stability is managed in the closed-loop version by metal foil strain gauge sensors that allow fast, exact linear motion with very small linearity deviations of 0.1%.
