Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., Dec. 21, 2017 — Physik Instrumente LP has announced a line of compact linear and rotary stages driven by ceramic direct-drive motors. The patented ultrasonic motors provide smooth motion with high resolution and a high dynamic range. The self-clamping motor principle locks the stage into place, devoid of creep, once a target position has been reached. This intrinsic brake-like behavior comes at no extra cost and provides advantages that are not available with classical electromagnetic drive technologies. Two linear stages with 18- and 22-mm travel are available, as well as an XY stage providing...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2023 IssueSteering MirrorsPiezo and voice-coil steering mirrors from Physik Instrumente LP are designed for free space optical communications.
