Abstract
The arrangement comprises a filter region (10) filtering electromagnetic radiation and a shielding component (20) inhibiting propagation of electromagnetic radiation. The filter region comprises a central filter region (11) and a separate peripheral filter region (13). The shielding component comprises an aperture (21). The aperture is arranged above the central filter region. The central filter region and the peripheral filter region are optimized for different angles of incidence (α, β) and provided for measurements by individual sensor regions (18, 19).
Claims20
An arrangement of an aperture and a filter region for a sensor device, comprising:
- a filter region provided to filter electromagnetic radiation;
- a shielding component provided to inhibit propagation of electromagnetic radiation;
- an aperture of the shielding component, the aperture being arranged above the filter region;
- the filter region comprising a central filter region and a peripheral filter region, which are separate from one another;
- the aperture being arranged above the central filter region;
- and
- the central filter region and the peripheral filter region being provided with differently designed filters for individual sensor regions.
A filter sensor device, comprising:
- a body;
- an integrated circuit in the body;
- a sensor region;
- a filter region provided to filter electromagnetic radiation, the filter region being arranged above the sensor region;
- a shielding component provided to inhibit propagation of electromagnetic radiation;
- an aperture of the shielding component, the aperture being arranged above the filter region;
- the filter region comprising a central filter region and a peripheral filter region, which are separate from one another;
- the aperture being arranged above the central filter region;
- and
- the central filter region and the peripheral filter region being provided for individual measurements in a central sensor region and a peripheral sensor region of the sensor region.
