Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.

An optical sight, system, and method for a firearm. The optical sight includes a housing including a base. A first support and a second support extend from the base. A top support extends between the first support and the second support. The top support extends over an optical element and includes a surface adjacent to the optical element. A second cross member defining one or more openings between the first cross member and the first and second supports. An optical element supported by said housing between said first support and said second support. A reticle is displayed on the optical element.

An intensity adapting optical aiming system that automatically adjusts the intensity of the reticle to adapt to the light condition of the external light. The aiming system may be mounted to a weapon and the external light may be a weapon mounted light. The aiming system may include an illuminateable reticle and a light connector for transmitting light from the external light to the reticle.

An improved firearm laser sight comprising a pattern generating element and an enlarging lens for enhanced projection of sight patterns onto an intended target is disclosed. The device is meant to be an accessory for firearms of all types by comprising any standardized methods for attachment, and may serve to decrease the time needed to acquire an intended target before firing. The device may implement a variety of sight patterns that may be projected larger and in a more pronounced way, when compared to standard firearm sights, to provide a clear image that may be quickly acquired even over longer distances. The improved firearm laser sight may be made available with a red or green visible laser, an infrared laser, or an ultraviolet light depending on the intended use of the device.

An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.

A diopter adjustment device for an optical device such as a riflescope includes a first tubular member having overlapping left-handed and right-handed external threads, a second tubular member has internal threads mated with either the left-handed or right-handed external threads of the first tubular member, and a stop nut threaded onto the first tubular member via internal threads that are of opposite handedness as the internal threads of the second tubular member. A diopter lens is mounted in one of the first and second tubular members and movable therewith relative to the other of the first and second tubular members to adjust a diopter setting or focus of the optical device. Because the internal threads of the nut and the second tubular member have opposite handedness, the nut provides greater resistance to inward movement of the diopter lens than conventional locking diopter adjustments.
