Ideal for particle tracking and SR microscopy. Nano-LPS Series The Original and the Best! Since 2001, we have offered innovative low profile nanopositioning systems. The Nano-LPS Series continues the innovation with up to 300 microns motion (XYZ), picometer precision, high stability, 83mm aperture, 3rd party image/automation software compatibility. Ideal for super resolution and optical microscopy. Nano-F Series The Nano-F series are nanopositioner focusing elements with 100 or 200 microns of motion and offer an alternative to microscope piezo Z stages. Ideal for super resolution (SR) microscopy such as STORM and PALM imaging. The C-Focus System 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. It retrofits to most optical microscopes, offers dual mode operation and is simple to use. The C-Focus also helps stabilize microscope drift, an important factor in the new techniques of super resolution (SR) microscopy. Images provided by Pohang University of Science and Technology show the efficacy of the C-Focus system in correcting microscope focus drift 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. Nanopositioner Noise and Resolution 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.
