Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., Sept. 26, 2007 -- PI (Physik Instrumente) LP has introduced the N-310 Nexact miniature ceramic linear motor actuator for applications including laser tuning, nanotechnology, nanoimprinting, semiconductor and data storage test and production equipment, nanomanipulation and biotechnology. Nexact is a patented, high-precision linear motor actuator developed to bridge the gap between micro- and nanopositioning devices. At .5 cubic inch and 50 g (1.7 oz), the Nexact actuator is significantly smaller and more cost effective than its big "brother," the high-force ceramic motor Nexline, PI said. Nexact...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics.com April 2024 IssueNano-Focus ScannersThe P-725.1CDE1S and P-725.4CDE1S from PI are nano-focus scanner packages for applications including surface metrology, super-resolution microscopy, light sheet microscopy, and digital slide scanning...Promoted Content March 2023 IssueMad City Labs GmbH - Tools for the NanoscaleMad City Labs provides tools for the nanoscale for applications in photonics, microscopy, and physics.
