Abstract:
1. A telescopic sight for designating a weapon's point of aim when pointed at a target, comprising: a. an objective lens for forming a first image of the target, said objective lens having a first focal plane and an optical axis, b. an image-erecting means for converting said first image into an upright and laterally-correct second image, said image erecting means being positioned on the objective optical axis after said objective, c. an eyepiece lens for converting said second image into a virtual third image of the target for convenient viewing by an operator, said eyepiece lens having a second focal plane, said eyepiece lens being positioned on the objective optical axis after said image erecting means, d. a reticle for indicating the point of aim, said reticle being mounted coplanar with either said first focal plane or said second focal plane, and e. a first prism for lateral shifting of said first image on said first focal plane, said first prism having an apex and a base, said first prism being positioned on the objective optical axis between the objective lens and said first focal plane, said first prism being mounted such that it can move linearly along the objective optical axis, said first prism's linear movement being mechanically adjustable by the operator, whereby the operator can view and use said third image of the target for the purpose of aiming and adjust his point of aim by adjusting the linear movement of said first prism along the objective optical axis.
