Electric Field Measurement – Electro-Optic Probe: eoProbe | Kapteos

The eoProbe from Kapteos is a high-precision electro-optic sensor designed for vector electric field measurements in demanding environments. Based on the Pockels effect, it ensures non-intrusive field detection thanks to full electrical isolation and a metal-free sensing area.

Benefits

• Non-intrusive measurement: no disturbance to the measured field.
• Wide bandwidth: from 40 Hz to 40 GHz.
• High sensitivity: from 50 mV/m to several MV/m.
• Compatible with all media: including liquids (SAR-compliant).
• Operates in extreme environments: high voltage, plasma, antennas, etc.

Key Features

• Technology: Pockels effect (electro-optic).
• Frequency range: 40 Hz – 40 GHz.
• Sensitivity: 50 mV/m to several MV/m.
• Isolation: fully isolated, metal-free probe.
• Compatibility: oscilloscope, spectrum analyzer, VNA.
• Dimensions: compact and lightweight for near-field use.

Typical Applications

• High-voltage environments: partial discharge detection, component aging.
• Near-field antenna analysis: full vector measurement (amplitude and phase).
• SAR compliance testing: in liquid media simulating human tissue.
• Industrial plasmas: strong field measurement in confined areas.
• Research and development: electromagnetics, EMC, and more.

Additional Information

The eoProbe is part of a complete Kapteos measurement system, including the eoSense module, mounting accessories, optical fibers, and readout interfaces. Calibration services, long-term rental, and on-site demonstrations are also available.
