  • Apparatus and methods for performing wavefront-based and profile-based measurements of an aspheric surface
    Patent number: 9212901
    Abstract: Apparatus and methods for performing wavefront-based and profile-based measurements of an aspheric surface are disclosed. The apparatus includes an interferometric wavefront measurement system that collects wavefront-based measurement data of the aspheric surface. The apparatus also includes a profile measurement system that performs at least one non-contact profile-based measurement of the aspheric surface to collect profile-based measurement data of the aspheric surface. The measurements are performed without removing the aspheric element from a rotatable base. The two measurements are then used to form a combined measurement of the aspheric surface.
