Physik Instrumente (PI) has introduced the P-733.DD direct-drive, multiaxis piezo stages for applications in biotechnology, nanotechnology, nanomanipulation, nano-imprint, semiconductor and data storage test equipment, as well as scanning near-field optical, atomic force and scanning probe microscopy. Resonant frequency of 2.3 kHz allows scanning rates of hundreds of hertz for capturing transient data. Because of the devices' parallel-kinematics layout, the X- and Y-axes' dynamic performance is identical, resulting in higher imaging speed and better linearity. The stages are vacuum-compatible, achieve <0.3-nm closed-loop resolution and are equipped with capacitive feedback for lower noise.
