Abstract

14,623. Abney, W. de W. July 15. Cameras for three-colour photography. The three images are obtained upon the one surface a<4> by reflecting-mirrors b, b<1>, d, d' for which prisms may be substituted. For the three separate lenses B, C, D, a single tripart lens may be substituted. Compensating-lenses B', D<1> are used to equalize the focal lengths of each pair of lenses B, B<1> and D, D<1> with that of the lens C, or alternatively the lens C may have a compensating-lens for the central image. The adjustable screens e, e prevent too wide a dispersion of rays passing through the lenses B, D.
