Patent ID: 8735819

Claim:
A detector system with an optical function comprising: an electromagnetic radiation detector including a detector portion ( 21 ) a readout circuit ( 20 ) hybridization balls ( 23 ) and a filling material forming a protruding rim ( 30 , 45 ) around the detector portion in order to form supporting wedges ( 37 , 45 , 57 ) positioned between this detector portion and this readout circuit, an optical component ( 35 , 49 , 61 ), and a system for positioning and passively aligning the optical component with the electromagnetic radiation detector ( 21 ), which comprises the supporting wedges ( 37 , 45 , 57 ) configured to contact a leading surface of the optical component, for Z positioning of the optical component ( 35 ) by forming a desired void space (e) between the outer surface of the detector portion ( 21 ) and the leading surface of the optical component ( 35 ) which is less than 800 μm, and means for passive alignment in X, Y by means of holding wedges and/or holding balls ( 36 , 60 ), placed around the detector portion, and in contact with the leading surface of the optical component, the axes X, Y and Z being three axes perpendicular to each other.
