Abstract

To calculate aberrations of an optical system is to obtain its aberration coefficients. Solving this problem allows us to study the correction capabilities of the system and define the design parameters, ensuring the correspondence of its aberration properties to the required ones to a certain extent. Sometimes it is possible to obtain an objective with satisfactory characteristics only on the basis of aberration calculations (this primarily concerns diffractive objectives, see Chap. 7), but these results are more often the first approximation to the further numerical optimization of the system by ray tracing (see Chaps. 8 and 9, for instance).
