Abstract

The present invention relates to an improved off-axis optical sighting system for a weapon or the like to provide a means to infinitely vary the size of the dot image seen by the user's eye.

Claims (58)

1. An off-axis variable dot size sighting system comprising,

a housing having a sighting axis therethrough,

a transparent, non-magnifying sighting mirror lens mounted adjacent one end of said housing,

said sighting mirror lens having a concave spherical surface which has a focal plane,

a coating on said concave spherical surface of said sighting mirror lens which coating reflects a specified color but is transparent to all other portions of the visible light spectrum,

a light source mounted to said housing for projecting a beam of light toward said focal plane of said sighting mirror lens,

at least one control lens mounted adjacent to said light source and interposed in said light beam from said light source to focus an image of said light beam at said focal plane, and

a reflecting mirror mounted in said housing at an angle to said sighting axis to reflect said image of said light beam from said focal plane to said sighting mirror lens whereby said beam of light is collimated by said sighting mirror lens and reflected along said sighting axis to the opposite end of said housing,

at least one of said control lens and said light source being movable relative to the other to alter the size of said image of said light beam.

2. The system recited in claim 1 wherein,

said control lens is spherical in configuration.

3. The system recited in claim 1 wherein,

said light source is a light emitting diode.

4. The system recited in claim 1 wherein,

said light source includes a light intensity adjustment means adjacent to the output of said light source.

5. The system recited in claim 4 wherein,

said sighting mirror lens collimates and reflects a light dot generated by said light source and also transfers the ambient light coming through said sighting mirror lens.

6. The system recited in claim 1 wherein,

said housing includes a chamber adjacent to the side of said housing,

said chamber adapted to receive said light source and said control lens.

7. The system recited in claim 6 wherein,

said light source is movably mounted in said chamber.

8. The system recited in claim 6 including,

an aperture which communicates between said housing and said chamber and is used to support said control lens therein.

9. The system recited in claim 1 including,

a light mask substantially surrounding said light source.

10. The system recited in claim 1 including,

a power source connected to said light source.

11. The system recited in claim 10 wherein,

said power source is a battery.

12. The system recited in claim 1 wherein,

said control lens is fixed in position relative to said focal plane of said sighting mirror lens.

13. A zoom dot aiming system comprising,

a sighting support,

a mirror lens which is transparent and concave mounted to said sighting support,

a light source mounted to said sighting support and adapted to provide a light beam which is projected onto said mirror lens where said light beam is collimated and reflected by said mirror lens, and

a control lens mounted on said sighting support interposed between said light source and said mirror lens to form said beam of light into a dot of light,

at least one of said control lens and said light source being movable relative to the other to change the size of said dot of light.

14. The system recited in claim 13 wherein,

said control lens is spherical in configuration.

15. The system recited in claim 13 wherein,

said light source is a light emitting diode.

16. The system recited in claim 13 wherein,

said light source includes a light intensity adjustment means adjacent to the output of said light source.

17. The system recited in claim 13 wherein,

the sighting support comprises an elongated cylinder.

18. The system recited in claim 13 including,

a reflecting mirror mounted to said sighting support intermediate said control lens and said mirror lens to direct said dot of light to said mirror lens.

19. An off-axis variable dot size sighting system comprising,

a housing having a sighting axis therethrough,

a transparent, non-magnifying sighting mirror lens mounted adjacent one end of said housing,

said sighting mirror lens having a concave spherical surface which has a focal plane,

a coating on said concave spherical surface of said sighting mirror lens which coating reflects a specified color but is transparent to all other portions of the visible light spectrum,

a light source mounted to said housing for projecting a beam of light toward said focal plane of said sighting mirror lens,

a control lens mounted adjacent to said light source and interposed in said light beam from said light source to focus an image of said light beam at said focal plane of said sighting mirror lens whereby said beam of light is collimated by said sighting mirror lens and reflected along said sighting axis to the opposite end of said housing, and

means for moving at least one of said control lens and said light source relative to the other in order to alter the size of said image and the beam of light reflected by said sighting mirror lens.

20. The system recited in claim 19 wherein,

said light source produces a beam of red light.
