The double expansion of the wavefront deformation in Zernike polynomials over the pupil and the field-of-view coordinates is a powerful tool for lens design, testing, and alignment. It provides a compact description of the wavefront deformation of perturbed and unobscured optical systems over the field-of-view. The integral of the mean-square wavefront deformation over the field-of-view is simply the sum of the products of the norms of the polynomials and the squared global coefficients. Eight or ten global coefficients can provide a comprehensive centered system description. Only fourteen main additional global coefficients is sufficient for the description of perturbed and unobscured optical systems.
