VARIABLE MAGNIFICATION LENS SYSTEM

摘要

A 6-component zoom lens for use between fixed conjugates at magnification ranging from 1:1.02 to 1:0.615. The two outermost components and one inner component are movable relative to the remaining components to vary the focal length of the lens as it is moved between conjugates to vary the image magnification. The inner movable component helps to maintain a flat field over the entire magnification range.
