Abstract

482,733. Colour kinematography. CHRISTIANI. L., and MASCARINI, G. June 29, 1936, No. 18057. Void. Convention date, June 29, 1935. Addition to 441,907. [Class 97 (i)] In an optical system for colour kinematography according to the parent Specification, comprising a first objective b producing a real image of an object a at a<1>, and a second objective c<1> and prism system d to form a number of juxtaposed identical 'secondary images e<1>, e<11> a further objective c is provided between the image a<1> and the prism. A second prism may be provided close to the image plane to equalize the ,paths of the rays to the several parts of the images. An aspherical lens may be arranged close to the prism d, or this prism may be an achromatic combination.
