将一个面的表面类型设为扩展多项式（Extended Polynomial）后，extra data编辑框里的第二项norm radius是什么呢？应该怎么设置呢？ <Z c: zemax manual里的说明是“Normalization radius. All ray-intercept points are divided by this number to determine the x and y coordinates for polynomial evaluation.”，但是没看懂，请问大家怎么理解？ m

generally this should be the semi-diameter of the surface. What "normalized" implies that the maximum is scaled to 1 and the rest of the cooridnates are calculated as a ratio.. This is similar to Normalized Coordinates used for pupil interception. See the Normalized Field/Pupil Coorindates in the user manual. 4>gMe3]0 WbS 2w @ 8 Hope this helps ..
