Qnami's Diamond Probes - Quantilever™ Series

Quantilevers are diamond probes made with NV centers for scanning NV microscopy applications.
 
We designed this patented technology in our laboratory in Switzerland for optimised optical throughput and unique resolution. Our Quantilevers operate best with the ProteusQ microscope, but can also be used in custom environments.

Diamond Scanning Probes with a single NV center - Quantilever MX

The Quantilever MX series are diamond probes with a single-spin NV center for imaging of magnetic fields.

We designed this diamond probes series for magnetic imaging in nanoscale resolution. With a single NV at the apex of the tip, our Quantilever MX scans surfaces with extreme precision and allow non-perturbative analysis of a large variety of magnetic materials.

Combine this diamond probes series with our ProteusQ microscope to get the best possible result.

Diamond Probes for Nanoscale Resolution

Each Quantilever MX contains a single atomic defect used to deliver images with extreme precision. 

Innovative

QuantileverMX is based on a patented technology developed and owned by us. This makes it unique.

Precise

Each sensor behaves like a true single-spin momentum, allowing non-perturbative analysis of different materials with atomic precision.

Flexible

It works best with our ProteusQ microscope system but its not limited to it.

Combine our diamond probes Quantilever MX series with our ProteusQ scanning NV microscope for direct quantitative measurement of the magnetic field with minimal calibration requirements.

Your packaging can be re-used. Ship it back to us and you’ll get a discount on your next order. Questions? Get in touch with Felipe, he’s happy to help.

Scanning NV Applications

A tool for NV diamond plate characterization with 10nm resolution

Sergei Trofimov and Boris Naydenov from the Helmholtz Center in Berlin used Qnami Quantum Foundry diamond plates to achieve nanoscale quantum sensing with 13 nm resolution by combining confocal and atomic-force microscopy techniques.

Optimizing Off-Axis Fields for Vector Magnetometry

Paul Stevenson’s research at Northeastern University utilized the Qnami ProteusQ microscope to enhance vector magnetometry, allowing precise measurement of both parallel and perpendicular stray fields in complex materials like bismuth ferrite.

Parabolic Diamond Scanning Probes for Single-Spin Magnetic Field Imaging

Researchers developed diamond probes that enhanced nitrogen-vacancy center signal detection, enabling improved quantum sensing for Qnami Quantilever MX+ probes
