Picopositioner™ Performance

Picopositioner position noise power spectrum
Nano-METZ position noise power spectrum showing flat response at low frequencies with position noise floor of 400 femtometers per √Hz.

Don't just Think Nano®, Think Pico™!

Mad City Labs has improved the implementation of our proprietary PicoQ® sensor technology in order to minimize position noise for the best ever positioning resolution in the industry. As a result, our high speed, high performance stages with short travel range have moved beyond the realm of nanopositioning into picopositioning, leaving former competitors behind. Systems with so-called "high performance" capacitive sensors cannot achieve picometer resolution because of rising 1/f noise at low frequencies. The position noise power spectrum of the Nano-METZ is shown at left. Nanopositioners and picopositioners with PicoQ® sensors have a relatively flat position noise power spectrum at low frequencies and do not exhibit 1/f noise down to 0.001 Hz.

Selected products from our Picopositioner™ product line:
2D representation of 312 pm Si (111) atomic steps measured by AFM
312 pm Si (111) atomic steps detected using a picopositioner™ with PicoQ® sensor technology, measured by AFM.
Position noise is critical to the resolution of many applications including Atomic Force Microscopy (AFM). Mad City Labs metrology-class picopositioners can be used to build high resolution AFM systems that can detect picometer-scale features. Accurate measurements of single atomic steps in Silicon (111), shown to the right, demonstrate the capabilities of an AFM built with Mad City Labs picopositioners. Additional AFM performance demonstrations are available.

Nanopositioner Noise and Resolution

Nanopositioner position noise power spectrum 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 PicoQ® sensor technology that provides 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.
