Abstract

969,458. Optical objectives. AGFA A.G. May 1, 1963 [May 9, 1962], No. 17268/63. Heading G2J. In a three component objective of which the outer components are convergent doublets having convergent cemented surfaces convex towards the interior of the objective and of which the middle component is a bi-concave single lens, the front radius of the middle component is less than the rear radius and the front air space is between five times and ten times the rear air space. Prefera - bly the front radius of the middle component is between 0. 5 times and 0. 9 times the rear radius of that component. Optical data are given for one example as shown.
