Nano-METZ: a compact z-axis nanopositioning system designed for high speed scanning and ultra-low noise characteristics for demanding AFM and metrology applications. Featuring Mad City Labs proprietary PicoQ® sensor technolog® sensor technology
Mad City Labs has improved the implementation of their proprietary PicoQ® sensor technologyin order to minimize position noise for the best ever positioning resolution in the industry. As a result, their 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 below. 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.
