Abstract

An optical sight is provided and may include a housing having a base, a first post extending from the base, and a second post extending from the base. The optical sight may additionally include an optical element supported by the housing between the first post and the second post, a reticle displayed on the optical element, and an illumination system generating the reticle. A first actuation member may be disposed on one of the first post and the second post and may selectively control an intensity of the reticle by controlling an output of the illumination system.

Claims

1. An optical sight comprising:

a housing including a base, a first post extending from said base, and a second post extending from said base;

an optical element supported by said housing between said first post and said second post;

a reticle displayed on said optical element;

an illumination system directing light away from said base and toward said optical element such that said light travels through an area external from said housing prior to reflecting off of said optical element, said optical element reflecting at least a portion of said light received from said illumination system to generate said reticle; and

a first actuation member disposed on one of said first post and said second post and operable to selectively control an intensity of said reticle by controlling an output of said illumination system.

2. The optical sight of claim 1, wherein said illumination system is operable between a manual mode and an automatic mode.

3. The optical sight of claim 2, wherein said first actuation member is operable to toggle said illumination system between said manual mode and said automatic mode.

4. The optical sight of claim 2, wherein said first actuation member is selectively movable between a first state and a second state, said first actuation member operable to control said intensity of said reticle when said illumination system is in said manual mode and said first actuation member is in said second state.

5. The optical sight of claim 1, further comprising a second actuation member operable to selectively control said intensity of said reticle by controlling said output of said illumination system.

6. The optical sight of claim 5, wherein said second actuation member is disposed on the other of said first post and said second post.

7. The optical sight of claim 6, wherein said first post includes a first surface opposing said optical element and said second post includes a second surface opposing said optical element, said first actuation member being disposed on an opposite side of said first post than said first surface and said second actuation member being disposed on an opposite side of said second post than said second surface.

8. The optical sight of claim 1, wherein said illumination system includes at least one of an LED and a photo sensor.

9. The optical sight of claim 8, wherein said illumination system is operable in a manual mode and an automatic mode, said first actuation member is operable to control said intensity of said reticle by controlling an output of said LED when said illumination system is in said manual mode.

10. The optical sight of claim 9, wherein said illumination system includes said LED and said photo sensor, said photo sensor controlling said intensity of said reticle by controlling said output of said LED when said illumination system is in said automatic mode.

11. The optical sight of claim 10, wherein said first actuation member is operable to toggle said illumination system between said manual mode and said automatic mode.

12. An optical sight comprising:

a housing including a base, a first post extending from said base, and a second post extending from said base;

an optical element supported by said housing between said first post and said second post;

a reticle displayed on said optical element;

an illumination system generating said reticle;

a first actuation member disposed on one of said first post and said second post and movable between a first state and a second state; and

a second actuation member disposed on the other of said first post and said second post and movable between a first state and a second state, said first actuation member and said second actuation member operable to selectively control an intensity of said reticle by controlling an output of said illumination system.

13. The optical sight of claim 12, wherein said illumination system is operable between a manual mode and an automatic mode.

14. The optical sight of claim 13, wherein said first actuation member and said second actuation member are operable to toggle said illumination system between said manual mode and said automatic mode.

15. The optical sight of claim 13, wherein said first actuation member and said second actuation member are selectively and independently movable between said first states and said second states, at least one of said first actuation member and said second actuation member operable to control said intensity of said reticle when said illumination system is in said manual mode and one or both of said first actuation member and said second actuation member are in said second state.

16. The optical sight of claim 12, wherein said first post includes a first surface opposing said optical element and said second post includes a second surface opposing said optical element, said first actuation member being disposed on an opposite side of said first post than said first surface and said second actuation member being disposed on an opposite side of said second post than said second surface.

17. The optical sight of claim 12, wherein said illumination system includes at least one of an LED and a photo sensor.

18. The optical sight of claim 17, wherein said illumination system is operable in a manual mode and an automatic mode, at least one of said first actuation member and said second actuation member is operable to control said intensity of said reticle by controlling an output of said LED when said illumination system is in said manual mode.

19. The optical sight of claim 18, wherein said illumination system includes said LED and said photo sensor, said photo sensor controlling said intensity of said reticle by controlling said output of said LED when said illumination system is in said automatic mode.

20. The optical sight of claim 19, wherein at least one of said first actuation member and said second actuation member are operable to toggle said illumination system between said manual mode and said automatic mode.
