When rays are traced through an optical system, it is generally desired to send a ray from a specific object point through a specific point on the aperture stop. For rotationally symmetric systems, it is common to replace the aperture stop itself by the Gaussian entrance pupil. The analog for this procedure is described here for the case of asymmetric systems. This first-order procedure for determining the initial configuration of a ray can be supplemented by a method that adds a second-order correction. This second-order method, which typically yields better estimates for initial ray configurations, is also described. Examples illustrating the use of these methods are given.
