Paper Abstract

The design of optical systems can be aided by general guidelines to the ways in which the most highly-corrected systems are assembled. We suggest that the designer can employ some of the more effective methods of controlling aberrations in the form of sub-systems which are internally corrected. Present knowledge of this is documented in only a fragmentary way. In this work we attempt to identify the useful principles. We list six general approaches to the reduction of aberrations. Two of these are described as "avoiding" and "negating" aberrations and these are the ones which are selected for further study. They require the knowledge or discovery of particular systems, and these often lead to the best results. Avoiding aberrations requires certain specific types of component and surface which we call the "special cases" of aberration correction. We discuss why they are useful. Negating or cancelling aberrations implies the use of two or more separated elements, where an aberration is large in an intermediate space but can sum effectively to zero. The systems in which good cancellation is achieved are further examples of the special cases: they may themselves be used as parts of more complicated systems. We give examples from our own work in which such methods are employed.
