Abstract

495,931. Colour photography. OPTIKOTECHNA SPOLECNOST S.R.O., PREROV. Feb. 21, 1938, No. 5447. Convention date, Feb. 20, 1937. [Classes 97 (i) and 98 (ii)] To produce, from a single objective O, three component images adjacent one another in a single rank along a film F, a system comprising cemented prisms A, B, C, is employed, the surfaces 1, 1 and 2, 2 being semi-reflecting and the surface 3, 3 being fully reflecting. The density of silvering on the reflecting surfaces is such as to produce an equal density in the images formed behind each colour filter d, e, f. The film is fed from the container K<1> to K<2>. The prisms may be replaced by three mirrors.
