Abstract

A zoom cell has a main zoom cell body having a central axis, at least two fingers extending from the main zoom cell body parallel to the central axis, and at least two grooves separating the at least two fingers. A zoom cell system has at least two zoom cells disposed in an erector tube, with the fingers of the at least two zoom cells pointed towards one another, with the at least two zoom cells positioned such that the fingers of a first of the at least two zoom cells align so as to correspond with at least one of the at least two grooves of the other of the at least two zoom cells.

First claim

What is claimed is:

1. A zoom cell comprising:
a main zoom cell body having a central axis,
at least two fingers extending from the main zoom cell body parallel to the central axis, and
at least two grooves separating the at least two fingers, wherein the at least two fingers and at least two grooves are not evenly disposed about the main zoom cell body,
wherein the zoom cell has a width and an outer diameter, and
wherein the aspect ratio as defined as the width/outer diameter is from 0.2 to 1.4.

2. The zoom cell of claim 1 having from two to ten fingers and from two to ten grooves.

3. The zoom cell of claim 1 , wherein the at least two fingers and at least two grooves are evenly disposed about the main zoom cell body.

4. The zoom cell of claim 1 , wherein one of the at least two grooves has a greater arc length than the other of the at least two grooves.

5. The zoom cell of claim 1 , wherein the zoom cell has an aspect ratio from 0.3 to 1.2.

6. A zoom cell system comprising:
an erector tube having an inner diameter, and
at least two zoom cells positioned within the erector tube, each zoom cell having a main zoom cell body with a central axis, at least two fingers extending from the main zoom cell body parallel with the central axis and separated by at least two grooves, wherein each zoom cell has an outer diameter, as measured with reference to the outer surface of the fingers, which is the same, and further wherein at least one finger of each of the at least two zoom cells further includes a pin projecting outwardly away from the finger in a direction perpendicular to the central axis,
wherein the at least two zoom cells are positioned within the erector tube such that the at least two fingers of a first zoom cell align with a corresponding at least one of the at least two grooves of the other of the at least two zoom cells.

7. The zoom cell system of claim 6 , wherein the erector tube further includes at least two slots, and each of the pins of the at least two zoom cells engages a respective on of the two slots.

8. The zoom cell system of claim 6 , wherein the at least two fingers are evenly disposed about the main zoom cell body.

9. The zoom cell system of claim 6 , wherein the at least two fingers of a first of the at least two zoom cells are not evenly disposed about the main zoom cell body.

10. The zoom cell system of claim 6 , wherein the at least two grooves have different arc lengths.

11. The zoom cell system of claim 6 , wherein each of the at least two zoom cells have an aspect ratio from 0.3 to 1.2.

12. The zoom cell system of claim 6 comprising two zoom cells positioned within the erector tube, each zoom cell having a main zoom cell body with a central axis, two fingers extending from the main zoom cell body parallel with the central axis and separated by two grooves.

13. The zoom cell system of claim 12 , wherein the two fingers of each of the two zoom cells further includes a pin projecting outwardly away from each finger in a direction perpendicular to the central axis.

14. A viewing optic comprising:
a viewing optic body having an objective end, an eyepiece end, and a power ring for adjusting magnification; and
a zoom cell system comprising
an erector tube having an inner diameter, and
at least two zoom cells positioned within the erector tube, each zoom cell having a main zoom cell body with a central axis, at least two fingers extending from the main zoom cell body parallel with the central axis and separated by at least two grooves, wherein at least one finger of each of the at least two zoom cells further includes a pin projecting outwardly away from the finger in a direction perpendicular to the central axis, wherein each zoom cell has an outer diameter as measured with reference to the outer surface of the fingers,
wherein the at least two zoom cells are positioned within the erector tube such that the at least two fingers of a first zoom cell align with a corresponding at least one of the at least two grooves of the other of the at least two zoom cells, and

wherein a power ring is operatively connected to the zoom cell system.

15. The viewing optic of claim 14 , wherein the viewing optic is a scope.

16. The viewing optic of claim 14 , wherein the erector tube further includes at least two slots, and each of the pins of the at least two zoom cells engages a respective one of the two slots.

17. The viewing optic of claim 14 , wherein the at least two fingers of each of the at least two zoom cells further includes a pin projecting outwardly away from each of the at least two fingers in a direction perpendicular to the central axis.
