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. Very high sensitivity, combined with high measurement resolution Equivalent efficiency for measuring static and oscillating fields Direct, vector and quantitative magnetic field measurement Excellent stability due to rejection of thermal fluctuations Easy integration due to the small size of the remote sensor Can be operated at high or low temperatures or under pressure Magnetic field dynamics 0 to 1 mT Sensitivity 3 nT / √Hz Bandwidth DC to 300 Hz Sensor dimensions Millimetric (customisable) Distance between sensor and control unit 5m (more on request) Voltage / frequency (mains) 230V / 50Hz Power consumption < 20W Nominal operating temperature 20°C +/- 5°C* Max. storage temperature From -20°C to 55°C, humidity <65%* *Note : The WAINMAG-LF technology can operate in harsh environmental conditions, including higher and lower temperatures.

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
