Claim Text:
1. An infrared sensor for temperature sensing comprising a cap covering a substrate, an IR-radiation filtering window in the cap, the window being transparent to IR radiation from a source external to the cap, a first sensing element, comprising a set of N thermocouples on the substrate covered by the cap, whose hot junctions may receive radiation from a source external to the sensor, a second sensing element comprising a set of N thermocouples on the substrate covered by the cap whose hot junctions may not receive radiation from a source external to the sensor, first connection modules for connecting a number N 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 for outputting the combined outputs of the first and second sensing elements.
