Newton ring can be used to measure the curvature radius of plane-convex lens，but there is no uniform regulation on the tangent position of cross wire and dark ring in the process of measuring the diameter of dark ring．After data comparison，it is considered that the calculation results of the data collected when the two cutting are closest to the standard value．
