A sensor device () comprises an emitter device () arranged to emit electromagnetic radiation and having an emission region associated therewith. The sensor device () also comprises a detector device () arranged to receive electromagnetic radiation and having a detection region associated therewith, and an optical system (). The emission region is spaced at a predetermined distance from the detection region. The optical system () defines a plurality of principal rays, a number of the plurality of principal rays intersecting the detection region. The number of the plurality of principal rays also intersect the emission region.

Sensor device

The present invention relates to an integrated infrared sensor device, comprising a sensor substrate and a filter substrate. The sensor substrate has a back surface and a front surface opposite the back surface, in which the back surface has a cavity defined therein and the front surface has at least one infrared sensing element formed therein or arranged thereon, covered with a cap for protecting the at least one sensing element, e.g. against mechanical damage and dust, and/or against stray radiation. The filter substrate is arranged on the back surface of the sensor substrate such that the filter substrate at least partially covers the cavity. The filter substrate is adapted in shape and composition to transmit infrared radiation and to attenuate radiation in at least part of the visible light spectrum.

Infrared sensor package

An infrared sensor for temperature sensing comprises a cap covering a substrate; an IR-radiation filtering window in the cap transparent to IR radiation; a first sensing element comprising a set of N thermocouples on the substrate covered by the cap, whose hot junctions may receive radiation; a second sensing element comprising a set of N thermocouples on the substrate covered by the cap whose hot junctions may not receive radiation; first connection modules for connecting a number Nof thermocouples of the first sensing element, second connection modules for connecting a number Nof thermocouples of the second sensing; connecting means for connecting an output of the first connection modules of the first sensing element with an output of the second connection modules of the second sensing element, and an output of the combined outputs of the sensing elements.
