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? {T|sU\| Q 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? HgL*/d GtI]6t [attachment=31132] AdBF$nn[ [attachment=31133]

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. 0_b7*\x c SjgF&LD Hope this helps ..
