Paper Abstract

The definition of the Gaussian Principal planes is presented based upon the conventional criterion of conjugate planes with lateral magnification equal to 1. These Principal planes split and move depending on the gaussian width of the incoming beam and the focal length of the system. The object-image relation using the frontal distances referred to the Gaussian Principal planes becomes, in the classical approximation, to the usual formula of the lens. Graphical techniques are used to find the Gaussian Principal planes in a simple way. The use of these planes allows us to analyze resonators and to design optical systems in which the beam is in variant.
