Nitrogen-vacancy (NV) centers in diamond enable magnetic field sensors that operate at room temperature, with high sensitivity and stable, drift-free readings. Our customers integrate our NV-doped diamond into instruments deployed across industrial inspection, medical and biomagnetic imaging, semiconductor and materials microscopy, navigation, and scientific instrumentation. We supply the application-grade material; they bring the integration expertise.
How our customers use NV-diamond
Industrial inspection and non-destructive testing. NV magnetometry-based inspection systems detect internal flaws, microcracks, stress points, and corrosion in aerospace, automotive, energy, and metallurgical components — non-destructively, often without removing the part from service.
Quantum diamond microscopy. Wide-field NV magnetic imaging localizes electrical, magnetic, and biological signals at the micron scale. Applications span semiconductor failure analysis (2.5D and 3D packages, backside power delivery, wide-bandgap devices), materials science (magnetic mineralogy, paleomagnetism), and biological imaging.
Medical and biomagnetic imaging. NV magnetometers offer a room-temperature alternative to cryogenic SQUID arrays for magnetoencephalography (MEG), magnetocardiography (MCG), and emerging single-cell biomagnetic imaging research.
Quantum navigation. NV magnetometers serve as drift-free, vectorial magnetic references for navigation in GNSS-denied environments — aerospace, autonomous platforms, and underwater operation.
High-field magnetometry and scientific instrumentation. Ultra-stable NV magnetometers monitor and control strong magnetic fields in research laboratories, MRI systems, atomic physics experiments, and particle accelerators.
Quantum education and research training. Compact NV-based platforms bring real quantum hardware into university and engineering school curricula, supporting the training of the next generation of quantum engineers.
Each of these applications has a different specification footprint — and our customers know far better than us what their systems need. Our role is to deliver the diamond that matches.
What we offer
Form factor. Diamond plates up to a few mm², bulk monocrystalline (100–500 μm thickness) or as thin epitaxial layers (10–30 μm) grown on diamond carriers.
NV concentration. Typically 1–5 ppm — the working range for the wide-field ensemble sensors our customers most commonly build.
Isotopic engineering. ¹²C enrichment up to 99.95%, suppressing the ¹³C nuclear spin bath and extending coherence times.
Crystallographic orientation. (100), the standard orientation for ensemble vector magnetometers.
Surface finish. Mechanical polishing down to roughly 1 nm roughness, suitable for the great majority of integration architectures.
Integration
Our diamond integrates into the standard NV sensor stack — green laser, photodiode, and magnets. The integration design, signal processing, and calibration belong to our customers, who hold the application expertise. Our role is to deliver diamond plates engineered to their specification — including custom geometry, thickness, and surface preparation — and to iterate quickly across prototype generations alongside them.
Who this is for
Companies and laboratories developing NV-based sensors and instruments. Our current partners include integrators serving non-destructive testing, semiconductor inspection, quantum navigation, scientific instrumentation, and quantum education markets.
Maturity
Diamond quantum sensors span TRL 4 to 8 depending on application — from early commercial deployment in semiconductor inspection and education, to advanced demonstration in navigation and industrial NDT. The technology is mature enough for industrial use; what remains is application-specific integration and scale.
