PRODUCTS AND SERVICES

The E-413 amplifier can control a piezo tube in two or three directions of motion. The possible directions of motion of a piezo tube depend on the number of its electrode segments.

The V-308 from PI is a high-dynamics positioner used for microscope objectives, featuring a voice coil PIFOC focus drive. This positioner was created with an integrated weight force compensation, PIMag® voice coil motor, a crossed roller guide, and provides direct position measuring.

The DPT-E range of actuators by Prior Scientific are designed with capacitive feedback control to give precise positioning, accuracy, and speed.

The NanoScan OP400 from Prior Scientific is a nanopositioning Piezo objective scanner. There are many applications for this product including optical sectioning producing 3D images, autofocus systems for time lapse imaging, high content screening, surface analysis, wafer inspection, and scanning interferometry. 

Prior Scientific's NanoScan-SP range of Piezo driven stages are compatible with the Prior motorized stage as well as many common microscopes when using appropriate adapter plates. Applications for this series include live cell imaging, surface analysis, water inspection, and more.

The A-523 by PI is an air bearing Z tip/tilt stage with direct drive. The Z tip/tilt stage is ideally suited for high-precision applications including wafer inspection, fiber positioning, optics positioning, flat screen inspection, maskless lithography, and ultra-LED manufacturing.

The V-931 is a high dynamics PIMag® voice coil motor from PI that can be utilized in many application fields. Uses include beam stabilization, satellite communication, image processing and stabilization, laser micromachining/tuning/scanning, beam steering with large deflection angles, and many others.

The P-911KNMV from PI features a space-saving parallel-kinematic design, producing a low overall height of less than 90 mm and a diameter of only 100 mm. The NEXLINE® piezo stepping motor drives and integrated incremental sensors ensure a position resolution down to 0.1 µm in the linear axes.
