By tracing the paths of a terrific many (one hundred or maybe more) meridional and skew rays by way of a lens, with the assistance of the electronic computer, and plotting the assemblage of factors at which all these rays pierce the focal plane following emerging within the lens, a close approximation to the appearance of a star picture is often created, and a good suggestion on the predicted performance of a lens may be acquired.
