The Q.ANT Magnetometer enables highly precise magnetic field measurements. New everyday applications emerge due to its compact size and operation at room temperature.
The Q.ANT magnetic field sensor enables the measurement of magnetic fields in the range of 300 picotesla at room temperature.
Previously, this level of sensitivity was only achieved by sensor systems under very specific environmental conditions: cooled down to absolute zero at -273 °C (or -459.4 °F) or heated up to 150 °C (or 302 °F).
The Q.ANT benefits
Located at the heart of the sensor, becomes sensitive to magnetic fields by inserting an adjustment in the atomic lattice, called an NV doping
bring the NV dopings into a magnetic field-sensitive state
acts on the sensor
shines on the NV diamond and causes the NV doping to fluoresce with red light
Changes when the external magnetic field changes
Captures the fluorescence light
Processing of photodetector data
User-friendly display of the signal
NV magnetometry is based on nitrogen-vacancy centers in diamonds, which serve as extremely sensitive sensors for magnetic fields.
NV stands for “nitrogen-coupled vacancy” or “nitrogen-vacancy” in English. In an NV center, a nitrogen atom is placed in the diamond lattice structure instead of a carbon atom. Next to it is an empty position / vacancy.
