RV Shack, K Thompson
Optical Alignment I, 1980•spiedigitallibrary.org… The characteristics of the aberrations of an axially symmetric field are well understood.
Except for spherical aberration, which is constant over the field, each aberration type is zero at
the center of the field and increases with distance from the center accordingly to a power law
which depends on the aberration type, and the aberration field for every type is rotationally
symmetric about the center of the field. Moreover, for each type, the value of the aberration
coefficient can be calculated as the sum of contributions from each of the surfaces in the system. …

It is shown that, for each field-dependent aberration type, the effect of tilts and decentrations is to produce a more complicated field dependence and local orientation of the aberration without otherwise changing its character. Particular attention is given to astigmatism.
