PI's piezo flexure stages combine sub-nanometer resolution and guiding precision with minimum crosstalk.

Miniaturized stages and manipulators are essential in mobile applications for measuring and medical devices, in industrial microassembly or use for research, e.g. in UHV and non-magnetic environments.

PI offers a wide range of motorized linear stages to supply high-precision industrial markets like semiconductor and photonics, as well as high-end research. Vacuum versions are available for a large number of different models. Multi-axis compositions can be set up with adapter brackets or specialized vertical stages and compatible rotation stages.

Choose from the widest range of technologies the optimum for your special demands: Set-and-forget applications benefit from the specific features of piezomotors that provide excellent long-term stability, also for vacuum or nonmagnetic environments. Stepper and DC motor solutions are well-established and reliable for both industrial and research use.

PI offers stages with all kinds of motorization and guiding options: air-bearing, torque motor driven, motorized worm-gear coupled, tiny piezomotor stages and specialized goniometer stages with orthogonal tip-tilt mounting option.

Hexapods provide six degrees of freedom in the most compact package. In combination with absolute measuring sensors, software and motion controllers that make the most complicated motion profiles easy to command, PI hexapods answer industrial requirements.

All digital controllers made by PI are accompanied by an extensive software package.

The decision for a motion controller depends on the specific application situation. Various criteria, such as limited installation space, the number of axes or the type of control, determine which controller is the right one. PI offers a broad spectrum of controls and regulation concepts.

Piezoelectric ultrasonic transducers are available in a wide range of shapes like disks, plates or tubes, and different performance levels. They can be adapted to application requirements by using different piezoceramic materials, electrodes, and assembling technology.

The term "scientific instrumentation" covers a variety of different applications, starting with microscopy via beamline processes through to the wide field of laboratory automation.

Imaging processes increase efficiency across a number of fields, ranging from medical engineering to pharmaceutical research and manufacturing of semiconductors.

Silicon photonics allows data rates into the Tbit/s range and is therefore suitable for computer-aided services that require the highest possible transmission speeds.

Progress in pharmaceutical research, diagnostics, and therapy requires high-performance and precise position systems. In addition to high positioning precision, requirements for the drives often include compact dimensions, low energy consumption, speed, and high reliability.

Efficiency has become an important buzzword these days. Materials research has paid a major contribution as the results have, for example, optimized processing methods. Methods such as X-rays and lasers or white light interferometry demand precise positioning of the specimens to be examined and of optics or beam control.

Mechanical engineering and manufacturing technology require fast, reliable and energy-saving drive components. The spectrum ranges from piezo actuators to six-axis parallel kinematics which can communicate directly with CNC controls.

Piezo drives, magnetic direct drives, and hexapods are part and parcel of automation today. They operate precisely and reliably and have proven themselves under rugged conditions.

Scientific experiments pose their own challenges, and beamline X-ray experiments are even more special in themselves. However, the need for precision equipment is universal.

PI Ceramic offers a wealth of experience in the manufacturing of piezoceramic materials, components, and actuators. The piezoceramic materials can be adapted individually to perfectly fit the later use of the piezo components.

Depending on the configuration and control, piezoceramic actuators can be used to create translational motions or as motors with a virtually unlimited travel range. The choice of drive depends on the requirements of the application.

Rotating electric motors such as DC or stepper motors are used in connection with screw or worm drives. Stepper motor systems with high-resolution encoders can perform minimum incremental motions of 10 nm with high reliability and repeatability.

In a parallel-kinematic, multi-axis system, all actuators act directly on a single moving platform. This means that all axes can be designed with identical dynamic properties, thus reducing the moved mass considerably. Hexapods are used for moving and precision positioning, aligning and displacing loads in all six degrees of freedom, i.e., three linear and three rotational axes.

The linearity and repeatability achieved are not possible without highest-resolution measuring devices. Accuracies in the range of a few nanometers and below require a position measurement method that can also detect motion in this range.

Fast settling or extremely smooth low speed motion, high positional stability, high resolution and high dynamics – the requirements placed on piezo systems vary greatly and need drivers and controllers with a high degree of flexibility.

Flexure joints, mechanical guide components or magnetic bearings? Which kind of guiding system PI uses in its products depends on parameters such as travel range, required precision, load, lifetime, and ambient conditions.
