Characterisation of Diamonds

Quantum Diamond Scan

Quantum Diamond Scan

the service for quantum characterisation of diamonds

The nitrogen-vacancy (NV) centre is an atomic defect in the diamond lattice. It consists of a nearest-neighbour pair of a nitrogen atom, which substitutes for a carbon atom, and a lattice vacancy.

The NV centre possess unique quantum and optical properties, which allows numerous applications including magnetic field sensing.

Successful applications of NV diamonds require an accurate understanding of the properties of the NV centres, optical or quantum. As NV diamond users, at WAINVAM-E we have developed characterisation tools to determine the quantum quality of our diamonds.

Manufacturers, users of quantum diamonds … we put our skills and our equipment at your disposal, to characterise your NV centres diamonds, or diamonds containing other coloured centres.


We offer a fast response and analysis, with a dedicated measurement bench.


You can choose what kind of tests you want, among the proposed analyses, or directly get in touch with us to define the test program.

Quantum Diamond Scan
notably includes

The measurement of the longitudinal relaxation time T1 and the quantum coherence time T2* of the NV- electron spins, in bulk diamonds or in nano-diamonds.

A photoluminescence spectroscopy analysis, to analyse the coloured centres present in a diamond.

The measurement of maps to understand strain inhomogeneities can be studied on request.
