Paper Abstract

Today's high performance cine lenses rely more and more on the use of aspheres. These are as powerful in correcting aberrations as they are expensive if it is not possible to use high-volume manufacturing processes. One possible solution to meet the increasing demands of design to cost is the use of identical parts in several lenses. The biggest gain is possible with the most expensive parts: the aspheres. In this presentation a successful as well as an ineffective way of incorporating the same asphere in three lenses which differ by a factor of 1.5 in focal length will be shown.
