Paper Abstract

Analytical expressions for evaluating zoom system parameters are given, along with properties of the resulting zoom system types. Relationships of the moving component are derived, taking into account overall dimensional limits, and are shown with two examples. The possibilities of reducing image defocus with zoom are discussed.
