Abstract

720,933. Optical systems. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE AUDE DELFT. April 28, 1953 [April 29, 1952], No.11727/53. Classes 97 (1) and 98 (1). An objective system comprises a concave spherical mirror having a corrector axially aligned therewith, the corrector comprises two meniscus lenses planal between the centre of curvature of the mirror and the mirror itself, and curved in the same sense as the mirror, the image plane being located between the two meniscus lenses. Data are given for one example of the system shown in which the lens VII is provided with a slot 14 through which a film 13 is led for photography or projection, the film being pressed against a support 15. Specification 638,975 is referred to.
