Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsPI (Physik Instrumente) LP has developed a P-652 piezoelectric linear-motor-driven translation stage that produces resolution of better than 0.1 μm. It contains a vacuum-compatible, nonmagnetic, self-locking motor made of an ultrasonic piezoelectric resonator and two lateral sliders connected to the resonator by a spring doubling. The stage measures 9.0 x 6.5 x 2.4 mm, can travel up to 3.2 mm and move at velocities up to 80 mm/s, and has a holding force of 0.2 N. It is designed for moving small objects such as fibers, optomechanical components, micromedical devices and micromechanics.See full productRelated content from Photonics MediaPRODUCTSPromoted Content December 2023 IssueCELESTA Light EngineLumencor’s CELESTA Light Engine houses seven solid-state lasers in a turnkey illuminator for demanding fluorescence applications like confocal spinning disk microscopy and spatially resolved...BioPhotonics.com April 2024 IssueSensor SystemThe AugaOne™ from ArgusEye is a sensor system that is meant to accelerate downstream monoclonal antibody process development by providing specific real-time and automated in-line data with high...Photonics.com 2/28/2023Piezo Objective ScannerThe Nano Scan OP800 piezo objective scanner from Prior Scientific Inc. features a mechanical design and integral capacitive feedback for positioning accuracy.
