Discover our 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 Qnami ProteusQ, but can also be used in custom environments.

Quantilever MX

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

We designed this series for magnetic imaging in nanoscale resolutionWith a single NV at the center of the tip, Quantilever MX probes scan surfaces with extreme precision and allow non-perturbative analysis of a large variety of magnetic materials. 

Combine it with the Qnami ProteusQ for the best possible result.

Quantilever DX

Quantilever DX are diamond probes containing multiple NV centers. The Quantilever DX present good brightness and are perfect to take  first steps into your measurement as well as for applications where high spatial resolution is not a requirement.

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 the 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.

Applications

Scanning NV magnetometry reveals magnetic textures in 2D material CrBr3 in cryogenic environment

/ /
Applying scanning NV magnetometry to cryogenic temperatures allowed Professor Wrachtrup and his collaborators to reveal magnetic domains and study their dynamics in atomically thin van der Waals magnets.

Characterization of room-temperature in-plane magnetization in thin flakes of CrTe2 with a single spin magnetometer

/ /
Using Qnami QuantileverMX probes, the team led by Vincent Jacques identifies the only “van der Waals” material known to date where magnetic order occurs in a few atomic layers even at room temperature 

Spatial Resolution in Scanning NV Magnetometry – Technical Note

/ / / /
This technical note explains how spatial resolution is defined in Scanning NV Magnetometry. For a given distance d between the NV center and the scanned surface, the best achievable lateral spatial resolution is 0.86 d.
