Abstract

1,018,717. Photographic objectives. CARL ZEISS-STIFTUNG, [trading as CARL ZEISS]. Nov 27, 1964 [Dec. 6,1963], No. 48292/64. Heading G2J. A wide angle objective having a field larger than Œ36 degrees has four groups the outer dispersive groups each consisting of at least two negative meniscus lenses concave to the diaphragm and the inner collective groups each consisting of a 3 lens cemented component having a central lens L IV , L VII in the form of an unsymmetrical biconcave dispersive lens tuning the surface r 7 , r 10 , of stronger curvature towards the diaphragm and is characterized by.
