MPI offers a huge variety of backlash-free MicroPositioners to address every operational and measurement condition, varying from small footprint to micrometer driven high-resolution positioners for RF and mmW applications. Unified Z-direction, ergonomic operation, and a strong magnetic base enable fine probe placement for high contact quality, producing unsurpassed measurement results.
MPI MicroPositioners are designed with universal interface compatible to all probe arms for ease of application specific adaptations. Design varieties allow operators to choose MicroPositioners which fit their operational familiarity, thus providing immediate proficiency.
The MPI self-developed MicroPositioners are designed without compromise. The full carbon-steel structure enables stable contact over long periods of time and superior positioning accuracy.
