eoProbe
Electromagnetic
field probes
The electric field and magnetic field probes eoProbe (RX optical antennas) allow a complete analysis (modulus and phase) of a single component of either the electric field or the magnetic field. Such analysis can be carried out on almost the whole radio-frequency spectrum concerning the E-field probes. The electromagnetic field assessment can be done with single-shot signals or repetitive signals. Moreover, this applies regardless of any environmental configuration or measurement constraint like near field, vacuum, high pressure, biological media, ionizing environment or strong magnetic or electric field.
Theses probes are compact, fully dielectric and contains only ultra low loss materials (quartz, alumina, sapphire). They provide a localized and highly accurate measurement of the electric field without any interference induced by the measurement.
This product is available in two lines for media with low or high permittivity.
eoSense
Optoelectronic converters
The optoelectronic converters eoSense embed one ultra low noise laser source and convert the optical information generated by the probes eoProbe into analog electrical signals that can be used directly by usual digitizers (oscilloscopes, spectrum analyzers or vector networks analyzers). They operate regardless the electric field strength, and they are protected against electromagnetic interference. They ensure KAPTEOS technology integration in any measurement chain.
Embedding the control of the field source and the digitizer, optoelectronic converters eoSense allow the monitoring of a comprehensive test bench in the frequency domain. They can also monitor optical multiplexers in order to sequentially address a large number of probes.
This product is available in different lines to cover all fields of application from 10 Hz to 100 GHz.

eoPod
Universal holders for probes
The articulated holders eoPod allow an easy positioning of one to three probes eoProbe (2 transverse and 1 longitudinal) in the measurement area, in almost any environmental condition (vacuum, phantom for SAR assessment, high voltage). These fully dielectric and handy holders have a built-in level and ensure reliable measurements.
They can be immersed, exposed to high magnetic field up to 4.7 T and they can be also directly in contact with high voltage elements up to 25kVrms.
eoCal
Electric field applicators
The electric field applicators eoCal allow to calibrate the electric field probes eoProbe in air up to 6 GHz. They have been specially developed for the probes eoProbe and ensure a perfect positioning of the probe in the center of the cell for an accurate calibration. They can be used also for EMC pre-compliance tests of electronic components or small PCB.
eoVac
Removable feedthroughs for low and high pressure
The removable and tight feedthroughs eoVac allow to use any probe eoProbe under high vacuum (down to mPa) or up to a pressure of 7 atmospheres. They can be used for applications implying either gases or liquids
eoSwitch
Optical multiplexer
The optical multiplexers eoSwitch allow a sequential addressing of up to 16 probes from a single optoelectronic converter. Without galvanic link, battery powered and shielded, they can be used in the field close to the measurements. They are fully driven by the optoelectronic converters eoSense through an optical link.
eoScan
electromagnetic
field scanners
The optoelectronic converters eoSense embed one ultra low noise laser source and convert the optical information generated by the probes eoProbe into analog electrical signals that can be used directly by usual digitizers (oscilloscopes, spectrum analyzers or vector networks analyzers). They operate regardless the electric field strength, and they are protected against electromagnetic interference. They ensure KAPTEOS technology integration in any measurement chain.

HENRI
Phantom for SAR assessment in operational environments
HENRI is a full dielectric phantom filled with human tissue simulating liquid. It is incorporating 16 points of interest corresponding to key organs and joints. It is dedicated to SAR assessment according IEC 62209, allowing accurate measurement of the 3 components of the E-field from 10 Hz up to 6+ GHz in both time and frequency domains.
