Abstract : An applied research program has been performed to produce a high energy photographic printing light source for exposure of high-resolution low-sensitivity non-silver-halide materials in a high-speed printer, that will produce 200 lines/mm to third generation. Two categories of light source were investigated, lasers and the plasma arc. The plasma arc was selected as the one light source presently available meeting the requirements for spectral emission, continuity of energy, and illumination output. An experimental apparatus has been constructed utilizing an optical system of reflectors and lenses. This optical system shapes the light from the light source to produce uniform illumination over the 10-inch dimension of the 1 x 10 in. aperture which is placed on the film plane. (Author)
