Performance increases can be realized by using aspheric lenses as opposed to spherical lenses, but designers have been hesitant to design in aspheres with diameters larger than 100 mm because of concerns about manufacturability and the availability of suitable metrology equipment. However, with advancements in both manufacturing and metrology, aspheres as large as 200 mm are now commercially available. To learn more, read the applications brief that begins on page 19.
