FIRST-ORDER ANALYSIS OF A 2-CONJUGATE ZOOM SYSTEM

A general analysis for the first-order design of the two-conjugate zoo m system, which consists of three lenses and has a real or virtual ima ge, is presented. The design formulas are derived. Of two-conjugate zo om systems, we analyze the solution areas in the system parameter diag rams under two particular initial conditions in which the object/image and pupil magnifications of the middle lens are taken to be 1 and -1 or -1 and 1. Two design methods are proposed. Several examples are giv en to demonstrate the proposed design procedures. (C) 1996 Society of Photo-Optical Instrumentation Engineers.
