All-In-One Quantum Diamond Microscope for Rapid Sample Characterization.

Negatively-charged nitrogen-vacancy (NV) defects in diamond possess optically pumpable spin states with long coherence times at room temperature useful to building highly-sensitive and robust magnetometers. For NV ensembles, a variety of factors can impact magnetometry performance, e.g. strain or nitrogen concentration, and numerous distinct setups are often required to fully characterize a sample. We present an all-in-one apparatus which combines many optical detection schemes into one platform, shortening the time required for characterization. Additionally, this design allows us to switch between multiple modalities and wide-field imaging, allowing us to correlate sample-wide parameter variation with performance.
