  • Patent number: 4940324
    Abstract: An electronic sight having a horizontal field of view greater than the vertical field of view. The electronic sight is mounted to pivot about two axes to provide windage and elevational adjustment. A windage adjustment screw includes a windage adjustment disk that extends from a base slot into a sight tube slot. The slot in the base is elongated in a first direction and the slot in the sight tube is elongated in a second transverse direction. Rotating the windage adjustment screw moves the windage disk to cause the sight tube to pivot about a vertical axis. An elevation jack raises and lowers the sight tube to pivot the sight tube about a horizontal axis. The sight tube has a raised rail on the top that acts as a key for aid in attaching and adjusting the battery assembly and light source relative to the sight tube lens. The sight tube includes grooves on an inner surface to aid in reducing the effect of glare from ambient light.
