<p>An exposure unit and method for imaging a photosensitive material includes a source of radiation for exposing the photosensitive material to actinic radiation such that the radiation strikes the photosensitive material at a plurality of angles of incidence, and apparatus for moving the radiation source relative to and in a plane parallel to the photosensitive material. The exposure unit also has a reflector for controlling (1) the proportion of (a) radiation having perpendicular angles of incidence to (b) radiation having non-perpendicular angles of incidence, such that the radiation having non-perpendicular angles is increased, and (2) the distribution of non-perpendicular angles of incidence.</p> |
