Non-interferometric measurement method for spherical lens surface profile via multiplane accelerated Wirtinger flow.

Spherical lenses are ubiquitously employed optical elements, and their surface profile errors can introduce significant negative impact on transmitted wavefront quality. Within the metrology of precision optical components, interferometry remains the gold standard for surface characterization. However, the interferometry necessitates sophisticated optical configurations that demonstrate susceptibility to environmental factors, coupled with the requirement for high precision reference mirrors corresponding to specific F-numbers of spherical lenses.
