PI (Physik Instrumente) LP offers a variety of piezo-driven precision positioners for high resolution microscope applications.The PIFOC family of fast objective focusing devices provide nanometer precise focus control and are also used in in 3-D imaging and Z-stack image acquisition due to their rapid, millisecond-range settling speed. Several devices are available to match different objective sizes and weights. Travel ranges from 50 µm to 2 mm are available. Instead of moving the objective lens, the sample can also be positioned with the PInano stage family of piezo-sample positioning and scanning stages.

The PInano stage family consists of more than 10 models of XY, XYZ and Z positioners with a variety of, travel ranges, apertures (for slides, well plates and petri dishes), and feedback sensors to suit any need from focusing to high speed 3-dimensional tracking.

The PIline family consists of several stages with long travel ranges to 100 mm and more, based on ultrasonic-ceramic piezo linear motors are available for “coarse” positioning with resolution in the 100 nanometer range. Due to their self-locking properties at rest, they provide better long-term stability than conventional motor-/lead screw stages. The ultrasonic motors also provide very high speed to 100 mm/sec and more.
