NV Advanced Modes Extension

Enhance your measurement capabilities

NV centers are sensitive to far more than DC magnetic fields. The NV Advanced Modes option extends both the hardware and software of the QSM, unlocking a powerful suite of measurement capabilities beyond standard ODMR.

Measurement protocols

The NV Advanced Modes option adds the following imaging and spectroscopy protocols:

  • Weak magnetic field imaging from nT to µT range
  • RF imaging via Rabi oscillations
  • Spin noise imaging via T₁ relaxation, T₂* Ramsey or T₂ Spin Echo / CPMG / XYN
  • Multimodal pixel imaging
  • Arbitrary pulse sequences

Custom pulse scripting

Arbitrary pulsing is supported by a dedicated pulse scripting interface in the QS3 software, enabling users to program, debug, and deploy fully custom pulse experiments for scanning measurements.

Accelerated scanning with Quickscan

The NV Advanced Modes option also enhances the Quickscan protocol, boosting scanning ODMR measurement rates to up to 200 pixels/s, dramatically increasing resolution within the same measurement time. Stay tuned as we plan to increase scanning speed even more in the future!

High sensitivity magnetometry

Working with weakly magnetic samples?

The NV Advanced Modes option enables measurement of samples with magnetic stray fields as weak as a few µT, or even down into the sub-µT regime. The Gradiometry Mode goes further still, resolving the smallest magnetic field gradients from your samples to within a few tens of nT.


For samples in the µT to tens-of-nT range, dedicated Quick Protocols maintain high scanning speeds without sacrificing sensitivity, giving you the best of both worlds.

Scanning T₁

Image surface spin noise

The NV qubit is exquisitely sensitive to even the smallest magnetic disturbances. While stray magnetic fields change the Zeeman splitting, local magnetic noise manifests as a change in the NV coherence time, a subtler but equally powerful contrast mechanism.


By measuring the NV coherence time during a scan, the QSM directly images the spatial distribution of magnetic noise from features such as domain walls. The image here maps the T₁ coherence time across a Bi:YIG sample surface, where domain boundaries appear as regions of elevated noise and distinct measurement contrast.
