WebFigure 1 shows a typical asphere drawing according to ISO-10110, with a depiction of the lens in the top center section that may include basic parameters such as diameter and center thickness. The material information is contained in the central region, and the left and right lens surface parameters are contained in the central left and right boxes, respectively. WebThese properties allow the light rays to converge in one point and the spherical aberration to be corrected. Thanks to modern production technologies, asphericon is able to manufacture aspheric lenses with highest precision even in series.
