Abstract
Historically, a thorough grounding in aberration theory was the only path to successful lens design, both for developing starting layouts and for design improvement. Modern global optimizers, however, allow the lens designer to easily generate multiple solutions to a single design problem without understanding the crucial importance of aberrations and how they determine the full design potential. Compared to pure numerical optimization, aberration theory applied during the lens design process gives the designer a much firmer grasp of the overall design limitations and possibilities. Among other benefits, aberrations provide excellent insight into tolerance sensitivity and manufacturability of the underlying design form. We explore multiple examples of how applying aberration theory to lens design can improve the entire lens design process. Example systems include simple UV, visible, and IR refractive lenses; much more complicated refractive systems requiring field curvature balance; and broadband zoom lenses.
