Abstract

Lens systems having external pupil positions are mainly used in connection with optical scanners. In consequence, these so-called f-(Theta) lenses show barrel distortion. This paper, however, is considering the front stop lenses (FS-lenses) poor in distortion and, therefore, suitable for photographic purposes.
