Abstract: A multi-axis motor includes a first elongate magnet member disposed in a first orientation and a second elongate magnet member disposed in a second orientation orthogonal to the first orientation and mechanically coupled to the first elongate magnet member. The first elongate magnet member is operable to adjust a first axis of a fine axis structure. The second elongate magnet member is operable to adjust a second axis of the fine axis structure.

Abstract: Systems and methods for controlling stray light reflections are provided. An optical system includes an aperture having an optical axis passing therethrough, one or more optical elements disposed along an optical path, and a detector disposed along the optical path. The system further includes an optical housing disposed between the aperture and the detector. The interior surface of the optical housing includes a predetermined surface feature adapted to control reflections of stray light along the optical path between the aperture and the detector. A method of fabricating an optical housing includes forming a pattern comprising a predetermined surface feature on an interior surface of the optical housing. The predetermined surface feature is configured to control reflections of stray light along an optical path between an aperture at a proximal end of the optical housing and a detector at a distal end of the optical housing.

Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through micro wedge mechanisms coupling the spacer to an inner and outer barrel. The inner barrel comprises a lens cell assembly and a body having a micro wedge slot. The outer barrel comprises a body having a micro wedge slot. The spacer comprises an inner barrel micro wedge and an outer barrel micro wedge. The spacer is configured to be physically coupled to the inner barrel through engagement of the inner barrel micro wedge and the inner barrel micro wedge slot. Further, the spacer is configured to be physically coupled to the outer barrel through the engagement of the outer barrel micro wedge and the outer barrel micro wedge slot.
