This EOFS Electric-field sensor is based on an electro-optical crystal packaged with a dual fiber collimator and made entirely of non-metallic materials. It features perturbation-free, wide frequencies coverage from Hz to microwave up to 40GH, high electrical damage threshold (>10 MV/m and 10W/cm2 power density), and harsh environment compatibility, including temperature, pressure, liquid, X-rays, and gamma rays. We produce sensors with both horizontal and particular sensors so that one can detect electrical fields in 3D. The readout is via a laser through optic fibers. It is ideally suitable to remotely and non-intrusively measure electric fields in a demanding application scenario.
We offer several package configurations for general use, liquid immersion, vacuum chamber compatibility, permittivity matching, and 3D vector sensing. Custom design is our specialty.
