In the previous chapter, we obtained the properties of a special two-surface optical system. We calculated certain of the Seidel aberrations and the primary chromatic aberrations of this system associated with its main focus. The next step in the development of the module is to determine the relationship between refractive indices, curvatures, thicknesses, and focal distances for which third-order spherical aberrations is identically zero. Then we will obtain a relationship between the height and slope of the chief ray that will result in zero third-order astigmatism. This will lead, in turn, to the definition of pupil planes in the three media for which third-order astigmatism is identically zero.
