Miniaturized Piezo-Motor Driven Nanopositioning Stage
Physik Instrumente (PI) recently introduced LPS-24 series of miniaturized, piezo-motor-driven linear positioners are less than one inch wide and provide 15 mm travel range with closed-loop sensor resolution up to 2 nanometers. The small dimensions make these new positioners anideal choice for high precision motion in confined spaces. A vacuum rated version is also available. These new reference class miniature positioners are equipped with a piezo-walk motor providing thrust of 5 N (1 lb). Users have a choice of two linear encoders, depending on the precision requirements of the application. The proprietary, high-resolution piezoelectric linear motor drive offers several operating modes: long distance, high-dynamics nanostepping (<1 nm resolution) and constant velocity mode. The self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake, another space and energy saving advantage of the LPS-24. With the patented PIone linear encoder, resolution of 2 nanometers is standard, and a 0.5 nanometer version is available on request. For lower precision requirements, a 150nm resolution sensor is offered.
