Paper Abstract

The two-group zoom lens is the simplest arrangement which is capable of achieving a modest useful zoom range and adequate aberration correction for practical implementation. The first order layout of these systems is straight-forward and the real battle that has to be fought is to balance the effects of vignetting and aberration stability. This paper reviews the `+-' type, the `-+' type and shows how the quality of the overall performance evolves with the redistribution of aberration correction between the two groups of the zoom system, finishing with the analysis of a practical system which uses a relatively complex construction to achieve high performance.
