Compact Nanopositioning Stage is Vacuum Compatible

19 Aug 2013

Auburn, MA, PI (Physik Instrumente) L.P. – a leading manufacturer of precision positioning equipment — offers the LPS-45 series of piezo-motor driven positioning stages manufactured by PI subsidiary PI miCos.

This compact closed-loop translation stage is driven by a PIshift inertia-type piezo motor. The stage is equipped with a high precision optical linear encoder providing for nanometer-level repeatability. An open-loop version and vacuum compatible and non-magnetic versions are also offered. Despite the compact dimensions and very low profile of only 15mm and, the stage offers a standard travel range 13 mm (1/2”) and 26 mm (1”) and can be scaled up for longer travel ranges, if needed.

Drive Principle: The PIShift piezo inertia drive is very quiet, due to its high operating frequency of 20 kHz. It provides high holding forces of 10 N. The drive principle works similar to the classic tablecloth trick, a cyclical alternation of static and sliding friction between a moving runner and the drive element.. PI provides a large variety of nanopositioning stages, based on several piezo-motor techniques, as well as classical electromagnetic drives.

Self-Locking: When at rest, the maximum clamping force is available, with no holding current and consequently no heat generation.

Software Support, Optimized Motion Controller A proprietary closed-loop controller eliminates backlash for nanometer-scale precision.

Applications PI’s precision linear translation stages are of great value for precision alignment in photonics, semiconductor, bio/nanotech applications as well as in scientific research.
