WebAspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example, aspheres can correct for … WebComputer Generated Holograms (CGHs) provide an effective means of quantifying the surface irregularity of aspheric lenses by converting spherical reference wavefronts into aspheric wavefronts that match the surface sag of the asphere. Aspheric surfaces are typically measured using scanning equipment, but using CGHs allow them to be …
