Quantum Diamond Microscope
Q-CAT QDM
The QDM by Q-CAT offers state of the art, wide-field imaging of magnetic fields, with applications spanning geoscience, bioimaging, electronics, materials characterization, and quantum research. It accomplishes this by using a quantum-grade diamond sensor doped with an ensemble of nitrogen vacancy defects to image the magnetic properties of samples. Robust and easy to use, this powerful microscope has a spatial resolution of less than one micron and a field of view up to four millimeters.
Highlights
- Image millitesla to nanotesla magnetic fields: Tunable spatial resolution down to less than one micron and field-of-view up to four millimeters in a single image. Larger samples can be readily mapped by tiling multiple images.
- Correlate Magnetic and Optical Images: Collect magnetic and optical images of samples using the same optical system for straightforward co-registration.
- Vector Measurements: The diamond sensor enables reconstruction of the magnitude and direction of magnetic fields, providing superior reconstruction of magnetic source distributions.
- Quantum-Grade Diamond: Manufactured by Q-CAT partner Element Six, with properties optimized for microscale magnetic field mapping applications.
- Robust and Easy to Use: Operates with no cryogenics, vacuum systems, special infrastructure, or power requirements.
Applications
- Quantum Research: The QDM is an accessible platform for research using nitrogen-vacancy (NV) defects in diamonds, including studies of NV ensemble spin properties and mapping of crystal lattice strain.
- Condensed Matter: QDMs have found applications in material science and condensed matter studies, such as probing thin magnetic films used for magnetic memory and the magnetic fields produced by current flow in graphene-based devices.
- Electronics: QDMs can be used to map the magnetic fields produced by currents flowing in electronic devices enabling high-resolution imaging of decapsulated chips, activity monitoring in intact devices, and board-level surveys.
- Rock Magnetism: The QDM is a valuable tool in remanent magnetization studies of geological samples.
