Nano-HS Series The Nano-HS Series is a high speed, multi-axis, precisionnanopositioning system with picometer positioningresolution Nano-View™/M Series Integrates manual micrometer 2-axis coarse positioning with a high resolution 2 or 3-axis nanopositioner. Nano-F Series The Nano-F Seriesare nanopositioner focusing elementswith 100 or 200 microns of travel and offer an alternative to microscope stage Z-axis motion 
Get Focused! Mad City Labs announces the introduction of the C-Focus positioning system. The C-Focus eliminates the effects of microscope focus drift by tracking and correcting the position of the objective lens from a user selected set point. The C-Focus system incorporates our picometer resolution piezo lens positioner with an easy-to-use controller for simple, stand alone operation. The C-Focus retrofits to most optical microscopes, offers dual mode operation and is simple to use. At Right: Typical microscope focus drift is of the order of 10's of microns. Engaging the C-Focus system eliminates focus drift quickly with high stability over long time periods. 
Mad City Labs provides the highest resolution nanopositioners available on the market today. Our nanopositioners have the lowest position noise and exceptional accuracy, which make them ideal for applications that require precision and sub-nanometer resolution. Mad City Labs' nanopositioners incorporate proprietary piezoresistive-based sensors, PicoQ™ technology, that provide a feedback signal to the electronic controller to eliminate creep and hysteresis caused by PZT actuators. Because of this, we can offer nanopositioners with sub-nanometer resolution and ultra-low position noise. For information regarding the issues of nanopositioner resolution, see the Laser Focus World article Understanding Noise at the Nanometer Scale. The article details the causes and limitations associated with nanopositioner resolution, and the processes involved in measuring it. The causes for these limitations are a result of the components of the nanopositioner as well as the surrounding environment, so it is important to consider all of the factors involved. In addition the article clearly demonstrates the superior performance of nanopositioners using our proprietary PicoQ™ sensor technology compared to nanopositioners using capacitance sensors. Note particularly the amazing stability of our nanopositioning systems at low frequencies where drift plagues capacitance sensors.For more information regarding nanopositioning resolution and the capabilities of Mad City Labs' nanopositioners, please refer to the noise plots for specific nanopositiong products. View the position noise spectra for nanopositioners like the Nano-LP Series and Nano-HSZ. Mad City Labs, Inc is a leading manufacturer of flexure based nanopositioning systems capable of sub-nanometer positioning resolution. Our product line covers the entire spectrum of nanopositioning capabilities while maintaining a leadership role in multi-axis stages for high speed optical microscopy imaging. Mad City Labs design engineers use 3D CAD and finite element analysis to produce nanopositioners which combine long ranges of motion with exceptional linearity, orthogonality, and stability. Our in-house CNC machining centers provide complete control of mechanical assembly production and allow Mad City Labs to design and fabricate custom systems with minimal engineering costs and short lead times. We deliver the tools for nanotechnology in 30 to 45 days and provide the highest level of customer service and satisfaction in the industry. Applications for nanopositioners include high speed confocal imaging, AFM, NSOM, scanning probe microscopy, fiber positioning, single molecule spectroscopy, single molecule tracking, high resolution optical alignment, and lithography. mclgen@madcitylabs.com phone: 608.298.0855 fax: 608.298.9525Copyright © 2008_uacct = "UA-2579961-1";urchinTracker();
