Abstract
798,132. Optical objectives. SOC. D'OPTIQUE ET DE MECANIQUE DE HAUTE PRECISION. March 20, 1956 [April 13, 1955], No. 8633/56. Class 97(1) An orthoscopic wide angle objective consists of two simple divergent lenses disposed one on each side of a pair of convergent groups of lenses each of which groups comprises at least three lenses and being disposed one on each side of a diaphragm. Numerical data are given for one example of the objective shown.
