Abstract
Devices and methods herein, in accordance with embodiments, provide a detector unit for an infrared (IR) imaging device comprising a focal plane array (FPA) of IR detectors configured to detect IR radiation intensity, and a detector unit lens configured to optically direct IR radiation onto the FPA and to protect the FPA from contamination. The detector unit lens and the FPA are integrated to form a detector unit that encapsulates the FPA, and the detector unit lens is configured to optically function as a common lens element for a plurality of different types of lens assemblies of the IR imaging device. Other embodiments herein provide for an IR imaging system, and for methods of manufacturing a detector unit.
