Abstract: Aspects are generally directed to a compact anamorphic objective lens assembly. In one example, the objective lens assembly includes a first anamorphic lens group including a first cylindrical lens having a surface optically powered in a first dimension and a second cylindrical lens having a surface optically powered in a second dimension orthogonal to the first dimension, the first anamorphic lens group being positioned to receive visible light along an optical path, a second anamorphic lens group positioned along the optical path to receive the visible light from the first anamorphic lens group, the second anamorphic lens group including a third cylindrical lens having a surface optically powered in the first dimension and a fourth cylindrical lens having a surface optically powered in the second dimension, and an aperture stop centered along the optical path and interposed between the first and second anamorphic lens groups.

Abstract: Aspects and embodiments are generally directed to compact anamorphic refractive objective lens assemblies. In one example, a refractive objective lens assembly includes a passively athermal anamorphic lens group including at least a first cylindrical lens having a surface optically powered in a first dimension, the first anamorphic lens group positioned to receive thermal infrared radiation, a focus cell positioned to receive the radiation from the anamorphic lens group, the focus cell including a first group of lenses each having a rotationally symmetric surface optically powered in the first dimension and a second dimension orthogonal to the first dimension, a relay lens group positioned receive the radiation from the focus cell, the relay lens group including a second group of lenses each having a rotationally symmetric surface optically powered in both the first and second dimensions, and a dewar assembly including a cold stop and an optical detector.

Abstract: A dual-field-of-view (FOV) optical imaging system having a primary FOV and a simultaneously viewable secondary FOV. One example of the system includes an imaging sensor, primary and secondary FOV objective optics configured to receive and output electromagnetic radiation corresponding to the primary FOV and secondary FOV, respectively, imager optics, and a field-of-view selection mechanism disposed between the secondary FOV objective optics and the imager optics and configured to selectively pass the second FOV to the imager optics, the imaging sensor being configured to produce primary FOV image frames and combined image frames that include imagery from both the primary and secondary fields-of-view.
