Low Field NV Magnetometer

WAINMAG-LF is a highly sensitive, vector and compact magnetometer. It can measure both static and rapidly oscillating magnetic fields, making it an ideal candidate for non-destructive testing of metal parts.

the Low Field NV Magnetometer for NDT

The WAINMAG-LF consists of a fibre optic point magnetometer, of milimetre size for easy integration, and a control unit.

The magnetic field measurement is performed by optical detection of the electron spin resonance of the nitrogen gap centre (NV).

To do this, the diamond is illuminated with a green laser, and the photoluminescence of the diamond NV centres under microwave (MW) excitation is collected and analysed.

This allows a direct vector measurement of the magnetic field in the sensor reference frame.

As the magnetic field measurement is very fast, the WAINMAG-LF can be used in an eddy current detection scheme as well as to locate static leakage fields of a defect in a material.

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

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
