Abstract: An optical sight with a rectifier and device for indicating turns of the rectifier includes a longitudinal body that houses sight elements coupled to the rectifier. The rectifier includes a rotatable control element and an indicator protruding from an upper surface of the rectifier. The indicator includes a longitudinal identification protrusion rotatable about an axis that is perpendicular to its length and parallel to an axis of rotation of the control element. A coding device is associated with the longitudinal identification protrusion and is mounted on the upper surface of the rectifier above an upper surface of the longitudinal identification protrusion, wherein a rotated position of the longitudinal identification protrusion relative to the coding device provides an indication to a user of the optical sight of turning of the rectifier. A zero stop mechanism is configured with the control element of the rectifier.

Abstract: A gun sight including a lens through which a target may be viewed and a light source for directing a point of light toward the lens, the point of light being reflected by the lens toward the viewer. The location of the reflected point of light with respect to the viewer along both windage and elevation axis is adjustable, and elevation and windage modules for permitting the adjustments are removable from the remainder of the gun sight without disturbing the adjusted and windage elevation settings.

Abstract: A telescope adapter for supporting a camera includes a light beam splitter for receiving light from the telescope and dividing that light into a monitoring bundle of light rays and a recording bundle of light rays, the two bundles of light rays being at angle to each other. The user is permitted to view the monitoring bundle of light rays, and the adapter can support a camera in a position to receive the recording bundle of light rays, so that the user and the camera can receive light from the telescope simultaneously. A first lens system is located between the telescope and the light beam splitter, the first lens system having a total negative power. A monitoring lens system receives and transmits the monitoring bundle of light rays leaving the light beam splitter, and a recording lens system receives and transmits the recording bundle of light rays leaving the beam slitter, both the monitoring and recording lens systems having total positive power.
