A normalization of the Delano y, ŷ diagram is proposed in which the y heights are normalized by the entrance pupil height, the ŷ heights by the image height. The normalization constants are expressed in terms of the system parameters, and it is seen that the reduced distances become normalized by the focal length of the system, the marginal ray reduced(More)
