Abstract
This paper describes a method of multiconfiguration or zoom optimization of optical systems using a conventional optical design program, even though the program was not explicitly designed to provide such a capability. This is accomplished by using the three indices of refraction that are accepted by the program (which are usually used to identify different spectral wavelengths) to identify different multiconfiguration or zoom modes. When using the indices for this mode identification purpose, it is not possible to control chromatic aberrations. There are, however, a number of design applications where a multiconfiguration or zoom optimization is required, but the control of chromatic aberrations is not. These ap-plications include all-reflective systems, laser systems or other narrow spectral bandwidth systems, and certain IR systems. Two procedures for utilizing the indices of refraction to represent multiconfiguration or zoom modes are the transparent mode method and the variable path method. Illustrative examples using both procedures are presented.
