Abstract
In this study, we take a data-driven approach to study the design efficiency of a variety of optical designs. Efficiency is defined to be the number of resolvable spots across the image per lens element. 3188 designs were selected from a commercially available lens database. Each design was imported into a raytrace code, briefly optimized, and the number of resolvable spots was computed. Examples of efficient designs within this dataset are shown. Four design efficiency groupings are created and discussed separately: 1) all-spherical, monochromatic designs, 2) monochromatic designs with some aspheres, 3) all-spherical, polychromatic designs, and 4) polychromatic designs with some aspheres. Zoom lens systems were excluded from the dataset. The results of the analysis are intended to answer the question of "how many elements does it take, as a minimum, to deliver a certain number of resolved spots?"
