KAPTEOS_SAS_The main advantages of our measuring vector electric field probes

In todays world, we are surrounded by electromagnetic fields (or EMF) generated by most electrical devices. To ensure that these devices do not cause interference with other devices, nor cause any health issues, the EMF generated by these devices much be measured to ensure that they meet EMC standards that strive to characterize acceptable limits.

The Kapteos Solution

After more than 15 years of Research and Development, Kapteos offers unique electro-optic probes to measure electric fields in harsh environments. These probes, based on the Pockels effect, are driven via an optoelectronic converter.
The Kapteos solution addresses worldwide industrial applications, institutes and research centers for measuring E-fields in:
the presence of High Voltage
inside Antennas for telecom, marine, aircraft, military
Cold plasmas
Magnetic Resonance Imaging (MRI) machine
Electro-Magnetic Compatibility (EMC)
Specific Absorption Rate (SAR) assessment

The Pockels effect

KAPTEOS_SAS_The Pockels effect


The Kapteos eoProbes are fully dielectric without any conductive parts. The eoProbes are based on a crystal which refractive index is modified in the presence of an electrical field. A laser beam is sent through the crystal. The laser modulation is changed in accordance with the E-field strength and returned to the converter. The effect is instantaneous and proportional to the E-field magnitude. There is no data loss of the measured field.
Kapteos has patented the ability of the laser polarization state to be the information carrier, versus optical modulation utilized by traditional optical transmitters.
