Precision Piezo Positioning Stages for High Resolution Microscopy by PI
(Nanowerk News) PI (Physik Instrumente) LP offers a large variety of piezo-driven precision positioners for high resolution microscope applications.
Fast Objective Focusing Devices – PIFOC® Family
Piezo-driven fast nanofocus devices not only provide nanometer precise focus control but they 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.
Piezo-Sample Positioning and Scanning Stages – PInano® Stage Family
Instead of moving the objective lens, the sample can also be positioned. 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.
Motorized Long Travel Stages with High-Stability Ultrasonic Drives - PIline® Family
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.
Piezo Beam Steering Mirrors
High speed piezo tip/tilt and beam steering devices scan laser beams in two coplanar axes avoiding polarization rotation errors typically induced by stacked single galvo scanners.
Controllers and Software
A variety of single and multi-axis piezo controllers for laboratory use and OEMs are offered.
Controllers are compatible with leading imaging software platforms such as Metamorph® and µManager, and LabView® and MATLAB® drivers are also available.
PI is a leading manufacturer of high precision positioning stages, piezo systems, piezo motors and actuators for microscopy, life science, bio-nano-technology, semiconductor and photonics applications. PI has been developing and manufacturing standard & custom precision products with piezoceramic and electromagnetic drives for 4 decades. The company has been ISO 9001 certified since 1994 and provides innovative, high-quality solutions for OEM and research. PI is present worldwide with 10 subsidiaries, R&D / engineering on 3 continents and total staff of 700+
