ABSTRACT:
An optical sighting device for firearms, more particularly hand guns and the like, geodesic instruments and the like comprising a telescope-type optical system with an objective and an ocular, or eyepiece, element and provided with a target mark, such as a reticle, positioned within the optical system, which is projected onto infinity, such as to be seen in the same plane as the plane of viewing of the target. The optical system consists of a massive cylindrical lens body of transparent material which has its opposite end surfaces formed as optically effective surfaces of symmetrical curvature, the surface of the objective being convex for converging the parallel light rays emitted from the target, and the surface of the ocular being concave for re-aligning the transmitted light rays to a beam of parallel rays. The target mark, or reticle, is disposed on the surface of the ocular element, and an image of the target mark is reflected and enlarged by the surface of the objective, such surface being provided with a semi-transparent mirror surface.
