Anatomy of an Asphere

An aspheric lens is a rotationally symmetric lens whose radius of curvature varies radially with distance from the center. It provides higher image quality, reduces the number of required optical elements, and significantly lowers the cost of certain optical systems. Aspheres can be found in digital cameras and CD players, high-end microscope lenses and fluorescence microscopes, as well as in other areas of optics, imaging, and photonics, as they offer significant advantages over traditional spherical optics.
