Abstract
Dry-process imaging apparatus for flash imaging an imaging film having a layer of an energy dispersible image forming material on a surface thereof. The apparatus comprises a source of electromagnetic or radiant energy, radiant energy collecting and guiding means, and support means including masking means for the imaging film. The apparatus is especially suitable for flash imaging microfiche cards, and enables an imaging energy source such as, for example, a Xenon flash tube, to be operated at lower energy levels for shorter time periods while achieving uniformity of energy distribution over a comparatively large area at the film plane.
