Paraxial analysis of mechanically compensated zoom lenses. 2: Generalization of Yamaji Type V

Appl Opt. 1982 Nov 15;21(22):4045-53. doi: 10.1364/AO.21.004045.


This paper presents a paraxial study of generalized Yamaji Type V mechanically compensated zoom lenses in terms of Gaussian Brackets. The expressions which define the displacement of components at zooming, the extremum of displacement, and the singular point of displacement are derived. Some numerical examples of the zooming locus are shown.
