Abstract
The combined aberrations of a concentric dome and a lens are discussed. It is shown that a major part of the aberrations cannot be directly attributed to the dome,but is caused by a drastic change in conjugates, which the dome imposes on the lens. Modulation Transfer Curves are presented for comparing the image quality of a highly corrected conventional photographic lens behind a concentric dome with the image quality of a dome-lens combination with integral correction. It is shown that the first approach should only be used for small apertures and field angles.
