title: Expression for aberration coefficients using nonlinear transforms--extension to spherocylindrical surfaces.
abstract: Previously we have used a matrix method to do nonlinear calculations and presented exact expressions for the third and fifth order aberration coefficients for a general conic surface as functions of the latus rectum and eccentricity. In this paper we show how the method can be extended to include the case of a general spherocylindrical surface.
