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: System and method for sensor alignment. In one example, a reimaging optical system includes reimaging foreoptics positioned to receive and reimage incident electromagnetic radiation to produce an intermediate image plane and output an optical beam of the received incident electromagnetic radiation, an imaging optical apparatus positioned to receive the optical beam and focus the electromagnetic radiation of the optical beam onto a first focal plane, a first imaging sensor positioned at the first focal plane and configured to produce a first image responsive to receiving the electromagnetic radiation of the optical beam, an alignment object selectively positioned at the intermediate image plane and configured to superimpose an alignment tool upon the first image, and a controller coupled to the first imaging sensor and configured to perform an alignment process for the first imaging sensor based on at least a position of the alignment tool in the first image.
