Abstract: The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and size, weight and power (SWaP) for the system is reduced. This also allows both subsystems (e.g., narrow field of view (NFOV) and wide field of view (WFOV) to use a single aperture and the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.

Abstract: The system and method for an additively manufactured radome for a cavity backed notch comprising at least one lattice structure wherein the antenna works over any 4:1 bandwidth, from VHF to mmW. In some cases, the radome lattice has a density that changes with distance from the antenna. In some cases multiple antennas are used for direction finding. The radome may be additively manufactured from glass-loaded polymer or other materials having a low dielectric constant. In some cases, the radome has a dielectric contract that approaches that of air.

Abstract: The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and swap for the system is reduced. This also allows both subsystems to use the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.

Abstract: A 3D-printed reflective optic providing very high specific stiffness through the utilization of a hollow shelled design, with closed back, filled with high-stiffness internal volumetric space-filling open-cell lattice structures. High-stiffness, structurally -integrated, sacrificial structures are also included for the purposes of reduction or elimination of tooling during post-processing operations.

Abstract: An athermal locking mechanism apparatus for large optic mounts is disclosed. The apparatus comprises at least one locking nut, at least one flexurized spring collet attached to a rigid base structure, a pivot shaft engaged with an optical yolk on a rotational axis of symmetry and a plurality of threads that joins the locking nuts with the flexurized spring collet The threads provide an increased level of a radial clamping force onto the pivot shaft, The interference generated between the locking nut and the spring collet causes all flexures to squeeze down onto the shaft, applying a purely symmetric radial force during the locking process. This eliminates any induced rotational torque and prevents the optical element from moving during the locking process after being properly aligned.
