Paper Abstract

It is discussed zooming loci of movable components in several types of mechanically compensated zoom lenses. They are a fundamental type (a variable afocal converter), a basic two-component type and a standard four-component type. A simultaneous zoom equation for each type, which satisfies simultaneously two paraxial requirements for zooming, namely, variation of paraxial value and stationary distance between an object and its image is derived. A set of analytical solutions to each type is obtained together with a numerical example. More general discussion is also added.
