KAPTEOS products and services

KAPTEOS offers a range of products and services that are tailored to the customer needs and constraints through their intrinsic performances. With fifteen years of development and continuous innovation, this range, available for sale and rental, is made up of 6 modular and interconnectable devices to meet your needs.


Electric field probes

Electric field probes eoProbe allow a complete analysis (modulus and phase) of a single component of the electric field on almost the whole radiofrequency spectrum, whether the field being a single-shot signal 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 field.

Theses probes are compact, fully dielectric and contains only ultra low loss materials (quartz, alumina). They provide a localized and highly accurate measurement of the electric field without any interference induced by the measurement.


This product is available in three lines: air, bio and vac.



Optoelectronic converters

The optoelectronic converters eoSense embed one or more ultra low noise lasers and convert the optical information generated by the probes eoProbe into electrical signals that can be used directly by usual digitizers (oscilloscopes, spectrum analyzers or vector networks analyzers). Regardless the electric field strength, they operate and are protected against electromagnetic interference. They ensure KAPTEOS technology integration in any measurement chain.


This product is available in different lines to cover all fields of application from 50 Hz to 70 GHz and more.


Electric field applicators

The electric field applicators eoCal allow to calibrate the electric field probes eoProbe in any medium (air, gases or liquids) up to 10 GHz for measurements carried out in air. They have been specially developed for the probes eoProbe and ensure the right configuration of the optoelectronic converters eoSense in accordance with your measurement conditions.


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.


Optical fiber extension cords

The optical fiber extension cords eoLink adapt to KAPTEOS measurement systems to allow a remote measurement from 15 to 95 meters. They are usable in both indoor and outdoor environments (for the rodent-proof ruggedized line) with the same constraints than the probes eoProbe and ensure a perfect signal quality regardless their length. They also secure the electric field measurements on emitting devices generating high field (high voltage equipment, electromagnetic pulse source, MRI, particle accelerator, etc.)


Removable feedthroughs for low and high pressure

The removable feedthroughs eoVac allow to use any air-line or bio-line probe eoProbe under medium vacuum or up to a pressure of 2 atmospheres.

A custom-made support

KAPTEOS is also a custom-made service and a global expertise to ensure the integration of its technology within your existing measuring system or the realization of a comprehensive turnkey solution. KAPTEOS means also available and trained people to work with you on the development of measurement solutions both unique, comprehensive and tailored to your configurations.

Create and co-create is our DNA.


KAPTEOS has achieved the following developments:

Anthropomorphic phantom for SAR assessment in operational environment (defense sector)

Human exposure to electromagnetic waves is a concern both normative and societal that can only be unambiguously resolved by a measurement. The current example refers to a phantom embedding 16 tri-axis electric field probes for measuring the soldier exposure in an operational environment on the 1 – 500 MHz frequency range. This development has been carried out on behalf of DGA (French Defense Procurement Agency).

Electric field measurement in railway environment

For both regulatory needs and monitoring of railway infrastructure parameters, 3D electromagnetic simulations and measurements carried out on line-powered scaled models allow the development of innovative surveillance assets of quantities of interest. This scaled model has allowed to study various influencing parameters (presence of a train on the track, attendance of maintenance personnel in different weather conditions such as fog).

Field mapping in a liquid phantom at 60 GHz

A calibration bench for measuring the dielectric properties (complex permittivity) of a liquid phantom at 60 GHz has been developed together with a SAR mapping device based on the measurement of the three components of the electric field vector inside the phantom. This calibration bench allows electric 3D field mapping with a strongly sub-wavelength spatial resolution.
