Ensuring designed function in freeform optics relies on narrow manufacturing and alignment tolerances. Legacy tolerance frameworks cannot easily capture the multi-dimensional deviations of asymmetric surfaces. Hence, integrating optical simulation into tolerance planning yields more meaningful manufacturing targets.
