ABSTRACT:
A device for flash imaging, through an imaging mask at an imaging film plane, a dry-process imaging film having a layer of an energy dispersible image forming material on a surface thereof. The device comprises a solid, electromagnetic energy transmitting body advantageously in the form of a quartz prism having a generally frusto-pyramidal configuration. The energy transmitting body is associated with a source of electromagnetic energy, and acts to collect, direct, collimate and shape the energy emitted by the source to provide maximum utilization and substantially uniform distribution of the energy at the imaging film plane. The device is especially adapted for flash imaging microfiche cards comprised of pre-formed areas or zones of an energy dispersible image forming material, and enables an electromagnetic energy source such as a Xenon flash tube to be operated at lower energy levels for shorter time periods thereby appreciably reducing energy costs and prolonging the useful life of the flash tube, while at the same time providing excellent image resolution in all directions in the imaging film.
