COMBINATION OPTICAL AIMING DEVICE FOR PROJECTILE WEAPONS

摘要

A combination optical aiming device comprises a non-magnifying sight that includes an optic and a magnifying sight that includes an eyepiece and an objective. To reduce the vertical distance between viewing positions for the sights, the optic and the eye lens are truncated in order to position the optic predominately outside of a projection of a perimeter of the eye lens, the projection being parallel to the optical axis of the objective.

主权项

1. A combination optical aiming device for viewing differently magnified images of a distant object from a common viewing plane, the combination optical aiming device comprising:
an erector system; a non-magnifying sight having an optic for viewing an image of an aiming point superimposed on a field of view of the non-magnifying sight from a viewing zone located within a common viewing plane; and a magnifying sight having an objective for gathering light from the distant object and an eye lens for viewing a magnified image of the distant object at an eyepoint also located in the common viewing plane, the optic and the eye lens being positioned relative to one another so that a horizontal plane that is both tangent to a base of the optic and parallel to an optical axis of the objective intersects a reference circle that surrounds the eye lens, touches at least one edge of the eye lens, and is centered about an optical axis of the eye lens, and the optic is positioned predominately outside of a projection of a perimeter of the eye lens, the projection being parallel to the optical axis of the objective.
