Since their development in 1999 by Mad City Labs, PicoQ® sensors have been proven to be the ideal direct measurement position sensor for nanopositioning applications, surpassing the capabilities of capacitive sensors in several critical performance areas. The development of PicoQ® sensor technology has enabled Mad City Labs to manufacture the fastest, most stable, lowest noise, and lowest profile nanopositioning systems available. Mad City Labs nanopositioning systems using PicoQ® sensor technology can be found in world-leading research laboratories and as high reliability OEM components in the most demanding industries.

All Mad City Labs nanopositioning products are rigorously tested before shipment. These tests involve a series of measurements designed to fully characterize the performance of the nanopositioning system with a realistic environment and testing conditions that match the application. Available metrology tools include NIST-traceable interferometers, high resolution atomic force microscopes (AFM), and a high resolution position noise analyzer, designed specifically for nanopositioning characterization.

Design of precision motion systems requires all of these well-accepted metrology tools. Any customer with a precision motion application should be comfortable asking for technical information, including the fundamental noise performance of the nanopositioning system. Mad City Labs is willing to provide applicable data. PicoQ® sensor technology consistently excels during testing under various application-driven demands and in various environments.
