Patent attributes
A multi-magnification viewing and aiming scope includes a first imaging group including an objective lens lying on the optical path and an eyepiece lens lying on the optical path. The first imaging group forms a first image having a first magnification on the optical path at an image location. A second imaging lens group is controllably inserted into the optical path between at least some elements of the objective lens and the eyepiece lens. Upon insertion of the second imaging lens group into the optical path an optical combination of the first imaging group and the second imaging lens group forms a second image having a second magnification on the optical path at substantially the image location. The insertion may be accomplished by a tumbler mechanism upon which the second imaging lens group is mounted.
