A New Type of Reflecting Sight

Not Accessible

Your library or personal account may give you access

Abstract

This paper describes a reflecting sight in which a mirror objective is used instead of a usual lens. The instrument becomes very small and the optical element is simple even for a large field of view. The astigmatism produced by the oblique reflecting plate is compensated by an off-center cylindrical lens. The problem is mathematically solved.
