It is crucial for the alignment to take place quickly and in a stable manner. For the new S-303.BL phase shifter, PI (Physik Instrumente) replaces classic piezo ceramic PZT actuators (made of lead titanate - lead zirconate) with pico

The new M-811.STV Miniature Hexapod from Physik Instrumente (PI) offers the perfect solution. Due to its compact design, with a diameter of only 130 mm and a height of 115 mm, the M-811.STV offers travel ranges of up

Compact, Digital Motion Controller for Nanopositioning

The single channel E-709 piezo controller from Physik Instrumente (PI) has been already introduced for piezo-based positioners and scanners which use strain sensors.

The biggest differences between the digital and analog controllers are that you can influence all parameters directly through calculation

Piezo-Based Linear Drive for Automation Technology

Linear direct drives have advantages over rotating electric motors for rectilinear motions in automation technology because the latter always have to use a spindle to convert the driving force into translational motion. An often undesirable aspect of conventional linear motors is that they are not self-locking and thus require holding currents which are associated with heat dissipation, high energy consumption and “positional jitter”. Piezo-based linear drives offer a solution here. Physik

They Go Through it With a Fine-Tooth Comb: PIFOC® Piezo Drives for Objectives

More and more techniques in microscopy, today, require an improved resolution. This often requires the combination of a large numerical aperture of the objective, that is a large clear aperture, and a large working distance along the optical axis. 3D images of living tissue are then possible, for example with the help of two-photon spectroscopy. For this purpose, PI now offers a PIFOC® piezo Z-drive for objectives with a clear

Industrial robot turns into precise machining system

Accurate machining is usually carried out with machine tools or machining centers. This means high costs and workpiece sizes limited by geometrical factors. It would be significantly cheaper and more flexible if industrial robots could be used instead, but their inaccuracy has so far made this impossible. This inaccuracy arises from the long serial kinematics chain with only low stiffness. A different approach is now possible. It has not been

Digital motion controller now also available for low-cost piezo systems

The E-709 singlechannel piezo controller from Physik Instrumente (PI) now opens up the digital technology and its advantages to lower-cost systems in the accuracy class from one to 10 nanometers. It will initially support the strain gauge sensors (metal foil or piezo-resistive) which are used in lower-cost piezo systems. The requirements placed on these systems mean that components with a well-balanced price-performance ratio are used in the E-709. The D/A

Fit for use in high vacuum

Positioning systems and linear actuators which operate on the basis of piezo ceramics are particularly suitable for use in high and ultra-high vacuum at pressures down to 10-10 hPa (mbar), because the motion is based on displacements in the crystal structure. Therefore no conventional mechanical elements such as shafts or gears are necessary and thus no maintenance or lubrication either. Neither is there a danger of an outgassing of the

Piezocube for 3D structuring

PI's range of high-precision stages – the NanoCube P-611 XYZ nanopositioning systems - prove their ability in new fields of application. The cube sides only measure 44 mm, making it suitable for travel ranges up to 100 x 100 x 100 µm and easy to integrate. The stages are driven by piezo actuators and achieve resolutions of up to 0.2 nm at response times in the millisecond range. The basic

XY stages with piezo linear motors – faster – low-profile – with new contr …

Physik Instrumente (PI) uses piezoceramic ultrasonic linear motors in many of its PILine positioning systems. This gives the stages not only a much lower profile but also makes them faster than comparable systems with motor/spindle drives. PI manufactures low-profile XY stages with a profile height of less than 30 mm across the whole surface of the stage – there are no lead screw ducts, no flanged motors. A speed of 100

Low-Cost Drive Electronics for Piezo Linear Drives

The compact NEXACT piezo stepping drives from Physik Instrumente (PI) push forward into a new performance class for linear drives: with high forces of 10 N, velocities of more than 10 mm/s, and at resolutions of a few nanometers they replace the typical stepper or DC servomotors in applications that depend on the combination of force and resolution on large travel ranges. The E-862 driver electronics is the ideal control
