Wide Field NV Imager

WAINIM-WF is a microscope that can quantitatively map the magnetic field produced by a millimeter sample with micrometer optical resolution. This makes it ideal for the study of micro-magnetic samples in fields such as geology or spintronics, as well as for imaging electric currents by reversing the Ørsted field.

the Wide Field NV Imager

The WAINIM-WF consists of a diamond with a layer enriched with NV centers.

This layer is illuminated by a green laser, and emits photoluminescence that is collected on a camera.

By scanning the frequency of a microwave and analysing the photoluminescence of each camera pixel, optical magnetic resonance detection can be performed.

The vector magnetic field at the NV centre layer can be traced.

Analysis of the field maps, using appropriate inversion models, allows the sources of the magnetic field to be traced back to any current or magnetisation.

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

The operation of a NV magnetometer

Magnetometry refers to the general principle of measuring the magnetic field of a system in order to study or characterise certain properties. The sensor with which magnetometry measurements are made is called a magnetometer. At WAINVAM-E we develop magnetometers using the optical and quantum properties


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

NV center diamonds and their production

A diamond is an organised assembly of carbon atoms, transparent to visible light. There are many natural diamond hues, often sought after in jewellery (Figure 1a-d), which are due to impurities and defects in the carbon structure that absorb light. The nitrogen-vacancy center Amongst these
