这就有了些疑问，为什么我选择的补偿器是近轴焦点，而分析结果近轴焦点都不变化？？应该是变得。另外最后的蒙特卡洛分析，只有10%的大于0.5（我用的是MTF作为评价方式），可是我设计的MTF如图 n[8ju,=  
zs|R#?a=  
)#n0~7 &  
是大于0.6左右的，难道我按照这个默认的公差来加工的话，只有10%的才可能大于0.5？那太低了啊，请问这该怎么进行进一步处理。或者之前哪有问题 LsH&`G^<

不吝赐教

一起学习下 p vone,y2  

     公差分析这里 我也不是很清楚 ，学习一下

我们导师说让用蒙特卡罗分析法，是不是skip sensitivity 模式？还有，geom MTF和 diff MTF有什么区别？

请问，公差设置的阿贝偏差应该设置成多少呢？

楼主 太强大了  能不能讲的 系统一些了 U}

好高深

好样的

额。。。请问你把敏感的公差调紧了后，百分比数有所变化吗？我也遇到同样的问题。。。
