Overview: ray transfer matrices - MIT OpenCourseWare
Overview: ray transfer matrices optical axis Propagation through uniform space: Refraction at spherical interface: distance d, index of refraction nleft radius R, indices nleft, nright By using these elemental matrices , we may ray trace through an arbitrarily long cascade of optical elements (provided the paraxial approximation remains valid throughout.).
