Abstract

701,396. Optical systems. WOOD, F. Oct. 22, 1951 [May 3, 1951], No. 10440/51. Classes 97(1) and 98(1) An objective system for a projector or photographic camera comprises a non-apertured spherical mirror 1 and a plane semi-transparent mirror 5 inclined to the axis of the mirror 1 to receive light reflected on to it by the spherical mirror and to reflect it on to a light sensitive film 6 or a screen to form an image. An aspherical or other correcting lens system may be located before the mirrors or the mirror may be formed on the rear of a lens system 4.
