Abstract

Several methods have been demonstrated for desensitization of a lens design to manufacturing errors with the result of increased as-built performance at the expense of a slightly reduced nominal performance. A recent study demonstrated a targeted desensitization method tuned for the most sensitive lens parameters can greatly increase yield for a known set of manufacturing tolerances. The effectiveness of such a targeted desensitization relies on two key pieces of information; lens sensitivities and manufacturing tolerance distributions. Targeted desensitization to known and unknown manufacturing tolerances is examined with an example demonstrating the impact of designing to unknown, bounded manufacturing tolerance distributions.
