The ProteusQ is the first scanning probe microscope making use of NV technology. It allows quantitative and non-perturbative analysis of surface magnetic fields at the nanoscale.
The QuantileverMX are diamond probes for scanning probe microscopy. Each QuantileverMX sensor behaves like a true single-spin momentum, allowing non-perturbative analysis of a large variety of magnetic materials such as antiferromagnetics, multiferroics, nanomagnetism, etc. Combined with the ProteusQ, the Quantilever MX provide a direct quantitative measurement of the magnetic field with minimal calibration requirements.
