Product Description

The MMP Series are nanopositioner-ready, stepper motor driven, micropositioning systems for high precision positioning for a variety of applications. Long range linear positioning is provided in one, two or three axis configurations with high resolution and excellent repeatability. Employing our proprietary intelligent control scheme results in exceptional stability with high native precision making our MMP Series the ideal choice for demanding motion control applications. Optional high resolution (50nm) linear encoders provide real-time feedback of the actual stage position. The included Micro-Drive™ controller connects to a PC via a standard USB port and can be controlled via the supplied LabVIEW based software. Complex motion profiles can be programmed and sophisticated control parameters such as automatic acceleration and deceleration is employed to achieve high stability and native accuracy. Optional wireless gamepad control is also available. The MMP Series is compatible with a wide range of our piezo nanopositioning systems and can be customized to your requirements.

For compatible nanopositioning systems, see the Nano-Met10 and Nano-Met20, Nano-HS Series, Nano-HS3M, Nano-OP Series, Nano-3D200, and Nano-SPM200.

The Ultimate Stability, High Native Precision and Accuracy of the Mad City Labs Stepper Motor Micropositioning Line

A related system, the single axis SPM-MZ, is often used for high stability, high resolution applications. The stability of the nanopositioner-ready SPM-MZ is critical to high resolution SPM experiments. The SPM-MZ was used as a Z axis coarse approach for the measurements below.

312 pm Si (111) atomic steps detected using a nanopositioner with PicoQ^® sensor technology, measured by AFM.

AFM Demonstrations: Measuring Atomic Steps
Measurements taken with an AFM show that nanopositioners with PicoQ^® sensor technology have sufficiently low position noise to accurately resolve single atomic layer size steps, 312 pm.
AFM Demonstrations: Sub-Nanometer Motion
100 and 450 micron range nanopositioners with PicoQ^® sensor technology perform 860 picometer steps, 1 nanometer sine wave, and repeated 95 picometer steps, externally measured by AFM.
AFM Demonstrations: Measuring Surface Roughness
AFM is used to externally verify that the position noise of a nanopositioning system with PicoQ^® sensor technology is less than the surface roughness of a Si (111) sample, 60 pm RMS.

The two axis MicroStage, designed for high resolution microscopy, also benefits from the stability and high native precision of Mad City Labs' proprietary intelligent control scheme. This can be seen below in the plot of extremely low drift after 150 micron motions.
