Paper Abstract

The principal function of the lens designer is the creation of an optical system which yields stigmatic imagery over a specified field of view, and often, over a wide spectral range. The modern lens optimization programs usually permit the designer to refine the mono-chromatic correction to a surprising degree, and choice of the optimum glass types will, without a doubt, result in further improved correction. Superior chromatic correction will probably never obtain, however, if glass types are not selected judiciously At the outset of the design effort. This is true of both field-dependent and axial types of chromatic defects, but the field-dependent defects are often more amenable to reduction through minor adjustments in system geometry. Reduction of axial chro-matic defects usually requires that major alterations be made in the configuration and this discussion will be restricted to reduction of only these image errors.
