Abstract: This invention discloses a riflescope wherein the point of aim is adjusted by attaching one or more corrector wedge prisms in front of the objective. Each wedge prism shifts the point of aim by a predetermined amount such as 5 cm at 100 m or 10 cm at 100 m, etc. A shooter can zero-in his rifle by first firing a set of test shots to determine how far off the bullets hit from the desired point of impact. He then selects one or more wedge prisms supplied with the riflescope and attaches them to its front side. The wedge prisms correct the riflescope's point of aim and bring it in alignment with the the rifle's point of impact. The riflescope introduced in this invention has no moving parts, no turrets and no off-axis optical components. There is no possibility of it's point of aim shifting due to rifle's recoil force or other vibrations. Additionally, the riflescope has a streamlined body which is aesthetically pleasing and also suitable for adding auxiliary sights such as a reflector sight.

Abstract: This invention teaches a binocular telescope wherein wedge prisms are positioned in the optical path of each telescope to control the amount of perceived parallax between the left and the right images. In one embodiment, a pair of thin wedge prisms are positioned in front of the objective lenses to optically manipulate the real convergence angle of an object viewed through the binocular telescope. In a second embodiment, wedge prisms are positioned after the eyepiece lenses to manipulate the apparent convergence angle of an object viewed through the binocular telescope. Depending on the position and the orientation of the wedge prisms, the invention produces benefits such as better depth perception, increased field of view, and the possibility to view close objects.

Abstract: A precision optical mechanism for adjusting the point of aim in telescopic gun sights is provided. A pair of thin wedge prisms are placed in the optical path of a telescopic gun sight such that they can tilt around an axis perpendicular to the optical axis of the sight. The sight's point of aim is adjusted by tilting the prisms.

Abstract: An attachment device that shifts the exit pupil position of a telescopic gun sight is introduced. The attachment includes a refracting wedge prism to tilt the viewing axis of the telescopic sight. This, in turn, shifts the position of the exit pupil of the telescopic sight and makes it possible to view the target image from an eye position offset from the sight's optical axis. The invention provides improved ergonomics for the shooter.

Abstract: A telescopic gun sight whose viewing axis is tilted with respect to the sight's main optical axis is disclosed. A refracting wedge prism is added to the optical layout of a telescopic sight after the eyepiece to tilt the viewing axis and provide an offset eyepoint. The tilted viewing axis provides better ergonomics when the telescopic sight is used in combination with other type of sights such as a reflex sight.

Abstract: This invention describes an ergonomic combination sight for small arms. According to one embodiment, the combination sight comprises a reflector sight mounted on top of a telescopic sight. A refracting wedge prism is included in the optical layout of the telescopic sight to tilt the viewing axis of the telescopic sight towards the viewing axis of the reflector sight. This feature provides better ergonomics since a shooter can aim through the reflector sight or the telescopic sight using the same head position.

Abstract: This invention teaches a weapon sight whose eyepoint is offset with respect to the sight's main optical axis. A refracting wedge prism is added to the optical layout of a telescopic sight to tilt the viewing axis and provide an offset eyepoint. The invention has several advantages including better ergonomics when used in combination with other type of sights such as open sights or reflex sights.

Abstract: This invention teaches a telescopic gun sight wherein the sight's magnification and point of aim can be adjusted simultaneously using the zoom knob. Once the sight is zeroed-in at a set distance, say 100 yards, it will automatically compensate for bullet drop at longer distances as magnification is increased.

Abstract: This invention teaches an optical method for adjusting the point of aim in telescopic gun sights. In one embodiment, a pair of prisms are placed behind the objective lens of a telescopic gun sight such that they can be rotated in a plane perpendicular to the optical axis. The sight's point of aim is adjusted by rotating the two prisms in opposite direction.
