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.

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.

A shock attenuation system configured to reduce shock experienced by an optical device coupled to a weapon includes an inner rail support configured to couple to the weapon and at least two outer rail supports substantially parallel to the inner rail support. The at least two outer rail supports are configured to couple to the optical device. The shock attenuation system also includes a first spring feature coupled to a first of the at least two outer rail supports and the inner rail support, and a second spring feature coupled to a second of the at least two outer rail supports and the inner rail support. The shock attenuation system further includes a viscoelastic material coupled to at least one of: the inner rail support, the first outer rail support, the second outer rail support, the first spring feature, or the second spring feature.

Method and apparatus for absorbing shock in an optical system

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 the coupling of a spacer to an inner barrel and an outer barrel. The inner barrel comprises a lens cell assembly and a body. The outer barrel comprises a body. The spacer comprises a body having an inner surface and an outer surface. The outer surface of the spacer body is configured to be physically coupled to outer barrel body and the inner surface of the spacer body is configured to be physically coupled to the inner barrel body. A retainer ring is configured to engage with the outer surface of the spacer body and provide a radial force against the outer surface of the spacer body to securably engage the inner surface of the spacer body with the inner barrel body.

Springless athermal lens design with flexured spacer

A system, according to an embodiment of the present invention, having an optical device and a shock attenuator is provided. The optical device is configured to operate with a weapon. The shock attenuator is disposed between the optical device and the weapon. The system includes the shock attenuator that is configured to reduce shock experienced by the optical device during operation of the weapon to less than 250 g's.

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.
