A lens assembly for a weapon sight includes a first lens having an optical axis and a focal plane array (FPA) coaxial with the optical axis of the first lens. A first parameter of the first lens is selected that minimizes an error in image shift when the weapon sight lens assembly is adjusted for focus. The first parameter of the first lens can be at least one of a lateral position, axial displacement, thickness, effective focal length, material, effective focal length, radius of curvature, conic constants, and higher order aspheric coefficients of the first lens. A sensor can detect a position of the lens and a processor can compare the measured position to an ideal position and use a lookup table to display a corrected reticle position or corrected scene. An actuator may move the lens to the ideal position from the measured position.

A firearm system includes a firearm and a computer. Electronics in the firearm determine data that includes a pathway between different points of aim of the firearm as the firearm moves. The computer receives this data and builds an image of the pathway between the different points of aim of the firearm.

A mount for attaching an optical scope to a weapon includes a base and front and rear lower clamping members extending from the base. The rear lower clamping member is axially spaced apart from the front lower clamping member. A front upper clamping member is attached to the front lower clamping member to define a front scope ring having a front cylindrical bore. A rear upper clamping member is attached to the rear lower clamping member to define a rear scope ring having a rear cylindrical bore, and wherein the front and rear cylindrical bores are co-aligned with a first axis. An accessory mount configured to receive a weapon accessory extends from the front upper clamping member and has an elongate portion extending along a second axis. The first axis and second axis are parallel and the second axis is laterally offset with respect to the first axis.

In accordance with the present invention, there is provided a gun sighting aid (10) including a body (12) configured to be mounted relative a substantially central longitudinal axis (14) of a barrel (16) of a gun (18) to be sighted, mounting means in the form of a fitting member (20) for allowing the body (12) to be displaced relative the longitudinal axis (14) of the gun barrel (16), a camera mounting means in the form of a camera mounting member (22) for allowing a camera (24) to be mounted on the body (12) to allow the camera (24) to be displaced coaxially relative the central longitudinal axis (14) of the gun barrel (16) and a data transmitting means in the form of a data transmitter (26) for transmitting data captured by the camera (24) to a remote display device (28).

A sight includes an inner lens barrel, a compensating device and a converting unit. The inner lens barrel includes a plurality of lenses constituting an optical axis. The compensating device includes a base, an adjusting unit and an adjusting cap. The adjusting unit is disposed on the base, is penetrated through the base and is placed against the inner lens barrel. The adjusting cap is connected to the adjusting unit, wherein the adjusting cap is rotated for axially moving the adjusting unit, and the inner lens barrel is pushed by the adjusting unit so that the optical axis is shifted. The converting unit is configured to convert shift amount of the optical axis to an electric signal corresponding to number of rotation of the adjusting cap and output the electric signal.

Systems and methods for calibrating, operating, and setting the magnitude of the power of light provided by a laser diode in a conducted electrical weapon (CEW). The light of the laser diode assists in targeting by providing a visible indication of the projected point of impact of the tethered electrode of the CEW. The calibration process enables laser diode of a CEW to operate within regional guidelines of the maximum output power of light permitted by a laser. The method further permits the magnitude of the power of the light provided by a laser diode to be set and operated in changing environmental conditions in the field.
