Method for assessing a vertex radius of curvature |
摘要 |
A method for determining a vertex radius of curvature for an optical surface. The method comprises subjecting the optical surface to a classical collimation testing procedure, so that the optical surface simulates a paraboloid; and, subjecting the optical surface to a vertex focusing interferometric testing procedure, so that a vertex radius of the optical surface can be determined.
