Abstract
A shielding element comprises a rigid substrate and at least one electrically conductive two-dimensional structure which is placed on one of the faces of the substrate. The substrate and the electrically conductive two-dimensional structure are such that the shielding element has optical-transmission and shielding-efficiency values at least one of which varies between two zones of the shielding element. Such a shielding element enables easier assembly of a detection system comprising multiple optical sensors.
