Fit for use in high vacuum
Piezo stepping drives from the NEXACT® or NEXLINE® range – also manufactured completely in ceramic and vacuum compatible – lend themselves for larger travel ranges. Depending on the version, positioning systems equipped with piezo stepping drives are suitable for travel ranges up to 30 or up to 125 mm and more. The positioning systems can cope with considerable loads. Heavy load versions achieve drive forces of up to 600 N, versions optimized for speed drive with speeds of up to 10 mm/s at a drive force of 10 N.
Other characteristics of piezomotors can also be advantageous: They do not need electric power once the position is reached. There is therefore no undesirable heat generation in the vacuum. Additional brakes are not required because piezomotors are self-locking when at rest.
Over the last four decades, the Karlsruhe-based company has become the leading manufacturer of nanopositioning technology. PI is a private company with healthy growth, more than 500 employees world-wide and a flexible, vertically integrated organization which enables PI to fulfill almost any request in the field of innovative precision positioning technology. All key technologies are developed in-house. This means that every phase from the design right down to the shipment can be controlled: The precision mechanics and the electronics as well as the position sensors and the piezo ceramics or actuators. The latter are produced by the subsidiary company PI Ceramic. PI has its own sales and service offices in all important markets. Moreover, the company maintains testing devices for nanometrology on three continents. PI Shanghai and USA have additional development and manufacturing resources which allow rapid local reaction to custom-engineered specifications.

New piezo nanopositioning system: versatile, fast and compact with large clear a …
Large clear aperture, high control dynamics, fast settling times and compact dimensions: PI launches a new product line of linear nanopositioning systems for a broad range of applications. The P-630 stages are perfectly suited, e.g. for use in sensor heads or precision motion of objects in optical and tactile metrology as well as for microstructuring. With travel ranges up to 80 µm and a direct piezo actuator drive, the compact positioning
2 mm Travel Range - 20 Milliseconds Settling Time: New Objective Scanner with Pi …
New microscopy methods, such as two-photon microscopy, make it possible to record 3D stacks with up to 1 mm depth in biological samples. For this they require high-performance drives for positioning the objectives. PI (Physik Instrumente) now developed the new N-725 PIFOC® objective scanner with piezo stepping drives especially for position-ing microscopy objectives. The N-725 provides travel ranges of up to 2 mm along the optical axis. At the same time
New Version of M-663 Micropositioning Stage: Benefits of PILine® Drive Technolo …
Cost-effective with 2 µm step size. PI (Physik Instrumente) completes its product line of high-velocity M-663 micropositioning stages. The new linear stage version M-663.5U is especially suited for positioning tasks in automation where a resolution of 0.6 µm and a step size of 2 µm are sufficient. The integrated PILine® linear motor provides push forces to 5 N and a maximum velocity of up to 250 mm/s over a 18 mm
Small Size and High Resolution: New Miniature Stage is Only 24 mm Wide at a Reso …
Physik Instrumente (PI) has introduced the new LPS-24 series. At only 24 × 33 × 20 mm³, these new miniature positioning stages provide a travel range of 15 mm with nanometer-precision resolution. The LPS-24 stages fulfil important requirements for the positioning of optical or mechanical components or for the adjustment and manipulation of samples in application environments with a confined space. For the LPS-24 series, PI uses NEXACT® piezo stepping drives. These
