The QDM.IO is the first system on the market which provides large area imaging of the magnetic field distribution using measurement based on nitrogen-vacancy centers implanted in a diamond. Conventional NV center-based microscopes use a single NV center in the tip and scan the sample, however, the heart of this microscope is a chip with many NV centers which can measure a large area simultaneously. The result is nanotesla sensitivity that not only detects the strength but also the local vector of the magnetic field. […]
