Imager optical systems and methods are provided. In one example, an imaging device includes a window configured to transmit electromagnetic radiation associated with a scene. The imaging device further includes a lens system. The lens system includes a first lens element configured to receive the electromagnetic radiation from the window and transmit the electromagnetic radiation. An aperture stop is positioned between the window and a surface of the first lens element adjacent to the window. The lens system further includes a second lens element adjacent to the first lens element and configured to receive the electromagnetic radiation and direct the electromagnetic radiation to the detector array. The imaging device further includes a detector array including detectors. Each detector is configured to receive the electromagnetic radiation from the lens system and generate a thermal image based on the electromagnetic radiation. Related methods and systems are also provided.
