Abstract:
1. A riflescope mountable to a weapon and having a field of view, comprising: a housing; an eyepiece mounted at a first end of the housing; a transparent optical window fixedly mounted at a second end of the housing opposite the first end; a guide track positioned within the housing between the first and second ends, and proximal of the transparent optical element; an objective lens system comprising at least one objective lens component, the objective lens system being operative to form a forward-most image at a forward-most focal plane of the riflescope, the objective lens component (a) having an optic axis, (b) being disposed entirely in front of and distal to the forward-most focal plane, and (c) being slidably supported on the guide track for lateral, non-pivoting movement of the objective lens component relative to the housing along a plane perpendicular to the optic axis; an aiming mark displayed in the field of view; and an adjustment mechanism operatively engaged with the objective lens component for driving the objective lens component laterally along the guide track in a straight line and along a direction perpendicular to the optic axis of the objective lens component to thereby shift an image of a distant target relative to the aiming mark in order to compensate for ballistic elevation or windage.
