Paper Abstract

There is need in the media industry to scan moving film images into computer systems for subsequent image processing. Scanning is used today mainly for the "digital intermediate" process - the whole film gets scanned and digitally processed. The industry demands projection lenses that are made in small quantities to very high specifications. This paper will describe an implementation of both projection lenses and associated illumination optics. Optical design theory, computer optimisation and production methods will be discussed.
