Confocal NV microscope

The WAINVIEW Microscope is a confocal fluorescence microscope that allows the observation of the fluorescence of the NV centers of diamonds, but also the determination of their quantum state. It reliably, sensitively and kinetically measures changes in pH and magnetic field in a variety of samples, including oil, water and cell environments.

the Confocal NV microscope

The WAINVIEW microscope is equipped with a variable power green laser source that can be adapted to the application. A pulsing system required for quantum detection allows the generation of very fast and precise sequences of light pulses. The incident beam is then directed towards the sample using a galvanometric mirror to scan the samples. The fluorescence signal from the diamonds is then detected by a photon counter, which allows us to identify a low level of fluorescence in the pulse sequence.
Our WAINVIEW Software transforms the optical data into numerical data, relevant to each application, for easy reading of the results.



WAINVIEW Microscope stands out from other equipment for detecting magnetic species because it is :


Fast, thanks to optimised scanning speed and signal processing


Reliable, as NV fluorescent sensors are extremely photostable (and do not exhibit photobleaching)


by choosing the specific diamond model for the desired application.


it can detect very small amounts and variations of magnetic field


Easy to use, thanks to the software developed specifically for this application


As only one drop of sample is needed on the usual microscope supports (slides, multi-well plates, Petri dishes, …)

WAINVIEW Microscope can be used to study a variety of samples in oil, water and cell media. It is therefore suitable for many detection and evaluation applications, such as :

Detection of fluorescent nano-diamond labels for biomedical research and diagnostics, as well as for anti-counterfeiting.

The detection of magnetic species, such as :
– Heavy metals in animal cells, for eco-toxicological studies
– Ferritin in animal and human cells for biomedical research and diagnostics

The detection of radical species in :
– Animal and human cells showing oxidative stress for eco-toxicological studies and bio-medical research
– Oils, lubricants and plastics showing oxidation

Evaluation of the efficacy of antioxidant molecules that neutralise radical species in an intra- or extra-cellular environment for agri-food  or pharmaceutical applications.

Detection of small temperature variations in a cellular environment for bio-medical research and diagnosis.

WAINVIEW Microscope works with the usual microscopy media (slides, multi-well plates, Petri dishes, …).

Quantum sensors

A quantum sensor is a measuring instrument that exploits the laws of quantum mechanics and provides the measurement of physical quantities directly from values of fundamental constants of quantum physics. Such a sensor is therefore inherently accurate and stable, both being essential properties for many

Oxidative stress

Oxidative stress is involved in many phenomena ranging from a simple burn to serious diseases such as cancer, infectious diseases or neurodegenerative diseases. It is promoted by internal mechanisms such as infections or deficiencies, as well as by external factors such as smoking, sun exposure

Functionalisation of nano-diamonds

The functionalisation of nano-diamonds refers to the modification of their surface that includes binding with chemicals or biomolecules (acids, proteins, etc.) to improve their properties and to bind them to specifically targeted locations with high precision [1,2]. Why is the functionalisation of nano-diamonds necessary? The


Metrology is the science of measurement. It defines the units of measurement, realises them, maintains their integrity, disseminates them and regularly leads to improvements in the international system of units. National metrology bodies serve as reference points for the calibration of measuring instruments used in
