OEFS：Optical E-Field Sensor

Our OEFS enables accurate E-field intensity measurement with a small sensor head utilizing the electro-optic effect.
It is used for various purposes such as verification of simulation model in EMC design, pulse E-field waveform measurement, measurement of high-power E-field and electric field measurement in a narrow space.
