Abstract
355,835. Colour photography. AUDIBERT, M., 17, Rue Victor Hugo, Villeurbanne, Rh¶ne, France. June 2, 1930, No. 17027. [Class 97 (i).] In an optical system for colour photography or kinematography, comprising a divergent objective C, D and a dividing system, such as objectives 01, 02, 03, for producing a number of images on a sensitive surface M, the divergent objective has its model points N<1>, N<2> in advance of the lenses so that the aperture of the objective 0<1,> 0<2>, 0<3> can be increased or the total length of the apparatus reduced. In an embodiment described the focal lengths of the lenses C, D are respectively 250 and - 90 mm. and these lenses are arranged so as to be almost in contact. A similar system may be used for projection. Specification 24809/11, [Class 97 (i), Optical systems &c.], is referred to.
