MATRIX 4 includes advanced AFM PLL hardware, developed through a strategic partnership with industry leader, Zurich Instruments. The new MATRIX 4 software interface offers all standard types of AFM measurements as well the flexibility to program custom control. There is a beginner mode for reliable and safe measurements, requiring minimum effort to initiate. Users can directly switch to an expert mode giving access to the complete parameter space of an AFM PLL with 4 digital, freely configurable demodulators. Preset options in MATRIX 4 for AFM perform high quality, high resolution AFM (either beam deflection or QPlus) with easy switching to other modes like Kelvin Probe Force Microscopy (KPFM) or spectroscopy with a few mouse clicks.
