Abstract: A light beam line projecting device having a combination of two or more lenses which magnify in only one dimension; i.e., cylindrical and plano-cylindrical lenses, which are arranged so that the lenses' physical proximity to one another can be manipulated in order to dictate the angle of light emitted from the lens system. The axes of curvature of the respective lenses are maintained in the same plane by a lens holder comprising a stationary lens holder which houses one of the lenses, a sliding lens holder which houses the other lens, and a rotating adjustment ring which provides both the outside housing for the system and the means of adjustment of the proximity of the lenses relative to each other. The sliding lens holder has projections that slide longitudinally in grooves in the stationary lens holder and projection that slide circumferentially in grooves in the rotating adjustment ring.

Abstract: A modular, combination laser and electronic aiming system is disclosed having an electronic sight portion and a laser sight portion. The electronic sight portion has a lens and a first light source for projecting a light beam upon the lens. The laser sight portion has a second light source for projecting a beam onto a target. Separate frames may be used to mount the first and second light sources and the lens to the shooting apparatus, and the frame for the laser light source may be disposed between the frame for the electronic light source and the lens, securing the laser sight portion to the shooting apparatus without interfering with the operation of the electronic sight portion.

Abstract: The modular aiming device comprises an elongated laser module operatively linked to a rechargeable power pack module. Rigid, quick-release clamps permit the hunter to mount the device alternatively upon an existing dove-tail scope mount or upon a pre-mounted optical telescope sight. A plurality of adjustable, padded scope rings may be employed to axially engage telescope sights of different diameters. A laser emitter diode is anchored within a tubular sleeve axially, adjustably disposed within the rigid laser housing. The laser sleeve comprises an asymmetrically planned, tubular, internally threaded shaft. Screw-driven, spring-biased, angular wedges associated with the sleeve cooperate with resilient flat springs to provide precision elevation and windage adjustments. Thumbscrew adjustments functioning as worm gears drive the wedges to tilt the laser sleeve horizontally and vertically relative to the laser housing.

Abstract: A laser aiming device having a plasma tube encased by a cylindrical member upon which windage and elevation adjustments act. Resilient ring members separate the cylindrical member from the plasma tube. Another resilient member located between the cylindrical member and an outer housing member cavity wall provides counterforces against which the windage and elevation adjustments act.
