Developed in the labs of QDM.IO co-founders Roger Fu and Ronald Walsworth, the QDM enables wide-field imaging of magnetic fields, with applications spanning geoscience, bio-imaging, electronics, materials characterization, and quantum research.
Quantum Diamond Microscope
Quantum Catalyzer
The Quantum Diamond Microscope (QDM) is a premier imaging tool based on nitrogen vacancy (NV) centers in diamond — providing non-invasive magnetic imaging with high spatial resolution and wide field-of-view.Developed in the labs of QDM.IO co-founders Roger Fu and Ronald Walsworth, the QDM enables wide-field imaging of magnetic fields, with applications spanning geoscience, bio-imaging, electronics, materials characterization, and quantum research.
Features

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.

Manufactured by QDM.IO 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.
New! Hyperfine Driving
Reach the same SNR three times faster with hyperfine driving enabled.
Software

Fully-integrated, python-based software with an intuitive graphical user interface enables users to quickly configure scans, monitor progress, and analyze data.
Real-Time Data Analysis
Convert raw hyperspectral imaging data to magnetic field maps in seconds using a suite of GPU-accelerated analysis tools, transforming the QDM user experience.

Built from the Ground Up for Wide-Field Magnetic Imaging
Continuously updated with new features and supported by expert QDM.IO technical staff.
