This paper reports the results of a treatment of a differential method for the fine correction of optical systems that is described at length in a Polish publication, which accounts for the extensive bibliography. The method is applied to various problems by deriving formulas for correcting one set of errors and at the same time, if desired, keeping another set of errors below a given tolerance limit.
