The rifle scope of claim 1, further comprising an inner tube pivotably mounted within the outer tube and holding an optical element for pivoting movement therewith, the jack screw operatively connected to the inner tube so that the optical element moves in response to rotation of the jack nut. 7. The rifle scope of claim 1 in which the jack nut includes a rear portion opposite the face, and further comprising: a substantially ring-shaped retention flange mounted on the outer tube, the retention flange surrounding the jack nut and including an internal shoulder abutting against the rear portion of the jack nut to rotatably contain the jack nut between the retention flange and the outer tube. 8. The rifle scope of claim 7 in which the retention flange includes an outer circumferential groove, and further comprising an index ring seated in the circumferential groove. 9. The rifle scope of claim 1 in which the set of face structures includes multiple circularly-spaced radial grooves. 10. The rifle scope of claim 1 in which the detent structure comprises at least one detent ridge. 11. The rifle scope of claim 1 in which the detent structure includes multiple detent members spaced apart such that not all of the detent members coincide with the face structures at any given time. 12. The rifle scope of claim 11 in which the face structures are evenly spaced and the detent members are also evenly spaced, and the number of the face structures are not an integer multiple of the number of the detent members, so that only one of the detent members registers with the face structures at any given time, thereby dividing each revolution of the jack nut into a number of increments totaling the product of the number of detent members times the number of face structures. 13. The rifle scope of claim 11 in which the face structures are evenly spaced and the detent members are also evenly spaced, and the number of the detent members are not an integer multiple of the number of the face structures, so that only one of the face structures registers with the detent members at any given time, thereby dividing each revolution of the jack nut into a number of increments totaling the product of the number of detent members times the number of face structures. 14. A mechanism for making incremental adjustments in a rifle scope, comprising: a body supporting a detent structure, the body adapted for mounting to an outer tube of a rifle scope to prevent rotational movement of the body relative to the outer tube; a spring operatively associated with the body for urging the detent structure away from the outer tube; a jack screw including a flat side surface for keying the jack screw to the outer tube to prevent rotational movement of the jack screw relative to the outer tube while allowing the jack screw to reciprocate relative to the outer tube; a jack nut adapted to be supported on the outer tube for rotation relative thereto, the jack nut threadably engaging the jack screw; and a face associated with the jack nut for rotation therewith, the face including a set of face structures opposite the detent structure of the body, the face structures spaced apart in a substantially circular pattern and sized to cooperate with the detent structure, the spring urging the body against the face with sufficient force to urge the detent structure into registration with one or more of the face structures, whereby, in response to rotation of the jack nut, the detent structure registers against the face structures with tactile clicks each indicating an incremental rotation and the jack screw moves an incremental distance with each of the clicks for adjusting the rifle scope incrementally. 15. The mechanism of claim 14 in which the body is formed on the spring, which comprises a substantially circular member with a convex surface. 16. The mechanism of claim 14, further comprising a cap covering the jack nut, the cap releasably engaging the jack nut. 17. The mechanism of claim 14 in which the face structures include multiple circularly-spaced radial grooves. 18. The mechanism of claim 17 in which the detent structure includes multiple detent ridges extending radially from a center of the body. 19. The rifle scope of claim 14 in which the detent structure includes multiple detent members spaced apart such that not all of the detent members register with the face structures at any given time. 20. The rifle scope of claim 19 in which the face structures are evenly spaced and the detent members are also evenly spaced, and the number of the face structures are not an integer multiple of the number of the detent members, so that only one of the detent members registers with the face structures at any given time, thereby dividing each revolution of the jack nut into a number of increments totaling the product of the number of detent members times the number of face structures. 21. The rifle scope of claim 19 in which the face structures are evenly spaced and the detent members are also evenly spaced, and the number of the detent members are not an integer multiple of the number of the face structures, so that only one of the face structures registers with the detent members at any given time, thereby dividing each revolution of the jack nut into a number of increments totaling the product of the number of detent members times the number of face structures. 22. In a rifle scope adjustment mechanism of the type having a manually rotatable member adapted for rotatable mounting on a rifle scope for adjusting the rifle scope, an improved detent mechanism for dividing each revolution of the rotatable member into multiple incremental amounts of rotation that impart incremental adjustments to the rifle scope, comprising: a body having a detent structure, the body adapted to be supported on the rifle scope and restricted from rotation relative thereto; a face associated with the rotatable member for rotation therewith, the face including multiple face structures opposite the detent structure of the body, the face structures spaced apart in a substantially circular pattern and sized to cooperate with the detent structure; and a spring operatively associated with the body to urge the body against the face with sufficient force to urge the detent structure into registration with one or more of the face structures, whereby, in response to rotation of the rotatable member, the detent structure registers against the face structures with tactile clicks each indicating an incremental rotation of the rotatable member thereby facilitating incremental adjustment of the rifle scope. 23. The mechanism of claim 22 in which the body is formed on the spring, and the spring comprises a substantially circular member with a convex surface. 24. The mechanism of claim 22 in which the face structures include multiple circularly-spaced radial grooves. 25. The mechanism of claim 24 in which the detent structure includes multiple detent ridges. 26. The rifle scope of claim 22 in which the detent structure includes multiple detent members spaced apart such that not all of the detent members register with the face structures at any given time. 27. The rifle scope of claim 26 in which the face structures are evenly spaced and the detent members are also evenly spaced, and the number of the face structures are not an integer multiple of the number of the detent members, so that only one of the detent members registers with the face structures at any given time, thereby dividing each revolution of the rotatable member into a number of increments totaling the product of the number of detent members times the number of face structures. 28. The rifle scope of claim 26 in which the face structur es are evenly spaced and the detent members are also evenly spaced, and the number of the detent members are not an integer multiple of the number of the face structures, so that only one of the face structures coincides with the detent members at any given time, thereby dividing each revolution of the jack nut into a number of increments totaling the product of the number of detent members times the number of face structures. nd output waveguide comprises an output optical fiber. 18.
