Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., Dec. 23, 2015 — PI (Physik Instrumente) LP has announced the P-915KWEF six-axis piezo hexapod for dynamic active error compensation. The device features a load capacity of 1500 g. A parallel-kinematic design with piezo actuator direct drives delivers results in a compact, stiff positioning solution compared to conventional multiaxis designs. A 1-kHz natural frequency is featured along with 1-nm linear resolution, 0.07-μrad angular resolution and positioning range up to 70 μm. The hexapod may be mounted inside rotary stages to virtually eliminate wobble and eccentricity errors, and can be...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueCustom Air Bearing Motion SystemsCustom air bearing motion systems from Physik Instrumente LP are designed to enhance performance in various industrial applications such as photonics, medical design, aerospace, and semiconductors....Photonics.com 3/13/2024Laser Welding PackagesAMADA WELD TECH’s ready-to-integrate laser welding packages are designed and bundled for quick adoption into an enclosure or onto a production line, so engineers can focus on other automation...Photonics.com 4/14/2023Linear Translation StagesThe PIglide A-123 family of wide-body, high-accuracy linear stages from Physik Instrumente LP are low-profile precision positioning stages equipped with preloaded air bearings and integrated linear...Photonics.com 7/19/2022Stepper Motor Linear SlidesL-836 Stepper Motor Linear Slides from Physik Instrumente LP are motorized linear translation stages designed for multiaxis stacking with an optional linear encoder and a compact folded drive train....ARTICLESPhotonics Spectra December 2023 IssuePhysik Instrumente Establishes Innovation Hub in KarlsruhePhysik Instrumente (PI) has established an “innovation hub” in Karlsruhe, Germany, as the company looks to intensify its cooperation with leading universities and research institutions....Photonics Spectra November 2022 IssueHollow-Core Fibers Enable Precise Positioning in SpaceA consortium led by researchers at the Fraunhofer Institute for Reliability and Microintegration (Fraunhofer IZM) is using hollow-core optical fibers to develop a reliable method to transmit light to...Photonics Spectra January 2024 IssueUV-based 3D Printing Accelerates Multipurpose Glass ProductionCurrent 3D-printing techniques for fabricating glass involve time-consuming processes that require high temperatures and considerable resources to complete.
