An optical system having a wide field of regard and a low profile comprises a first section with optically passive components stationarily fixed within the optical system for focusing optical energy associated with a field of regard received by the first section, and second section. The second section includes at least one gimbal drive assembly for establishing the field of regard by actively driving an additional optical component used to guide optical energy to or from the first section. The second section can include both an azimuthal gimbal drive assembly and an elevation gimbal drive assembly. The first section can be mounted to an interface structure, which pivotally mounted to the airframe of the vehicle. The second section can be rotatably mounted to the first section, so the first section remains stationary while the gimbals of the second section rotate.
