ABSTRACT:
A powered-zoom rifle scope is disclosed. The scope includes a body tube with an eyepiece mounted at an ocular end and an objective lens mounted at an objective end. A cylindrical zoom lens assembly is mounted at the objective end of the body tube and optically aligned with the scope. A cylindrical housing is positioned about the body tube at the objective end of the scope to encase the zoom lens assembly and to provide an annular space between the body tube and the housing. The zoom lens assembly has a ring-like zooming gear mounted proximate the objective lens of the scope. A miniaturized bidirectional motor and a plurality of batteries are mounted in the annular space with the motor mechanically linked with the zooming gear. A finger operable switch is mounted at the eyepiece of the scope and linked with the motor to allow the user to operate the zoom lens assembly while retaining a finger on the trigger of the firearm and the target image within the field of view of the scope.
