1. An array for detecting electromagnetic radiation, comprising:
a plurality of detector elements arranged consecutively along a scan line which extends in a first direction for receiving electromagnetic radiation and converting the received electromagnetic radiation into a detection signal;
wherein each of said detector elements receive the electromagnetic radiation on a detection surface which has a plurality of surface normals, such that the surface normals of each of the detection surfaces extend in a common plane in the first direction and converge into a common focus;
wherein the detector elements are arranged such that a distance from the common focus to at least two of the detection surfaces is different when each distance is measured along the surface normals of the respective at least two detection surfaces;
wherein an end surface of each adjacent pair of said detector elements are provided in a facing relationship, are aligned along a straight line that passes through the common focus, and all centroids of the detection surfaces are aligned along a straight line.
