ABSTRACT:
In a thermal imaging unit (12) including optics (16,18) for detecting a target scene (14), a detector array (26) responsive to target scene energy and a scanner (23) for scanning target scene energy from the target (14) onto the detector array (26), an imager lens assembly (120) for focusing the target scene energy onto the detector array. The imager lens assembly includes entrance means (126) for passing the target scene energy. The imager also includes both a first aspherical lens (122) for providing an intermediate focus of the target scene energy and a second aspherical lens (124) for receiving the intermediately focused scene energy and focusing the intermediately focused scene energy onto the detector array.
