| Abstract: | In this article the Newton reiteration is employed to calculate the cross point of rays intersecting a toric surface. The formulation is also offered. In summing up it may be stated that a toric surface can be used to describe the form deviation of optical elements. It provide a yardstick for the determination of the tolerance of surface form deviation. |
