公差分析结果的疑问

我现在在初学zemax的公差分析，找了一个双胶合透镜 AN:s%w2

然后添加了默认公差分析，基本没变 9-{+U,3)

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 6L8nw+mEK  
[attachment=34429] u$aK19K/  
iptA#<Yj  
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 / =6_2t#vA

不吝赐教

我又试了试，原来是得根据上面的结果不断修改公差，放松或者变紧，然后在做公差分析，不断提高蒙特卡罗的结果。但是比如就拿我这个来说，理想是达到30lp处>0.6，那么实际做蒙特卡罗公差分析时，百分之多少以上的MTF是合格的呢？

最后这个数值是MTF值呢，还是MTF的公差？ HU?1>}4L

也就是说，这到底是有90%的产品MTF大于0.20977951还是90%的产品的MTF变化量大于0.20977951？？？   j_90iP^5:

波长632.8nm 时 mtf 是 0.54403234  没达到0.6
sansummer 2011-06-24 09:37
谢谢。您说的“波长632.8nm 时 mtf 是 0.54403234  没达到0.6”这是一个评价标准吧？ >Du=(pB  
4#>Z.sf  
这个评价标准和我理想的设计结果的0.6有什么联系吗，另外这个 0.54403234  是这么来的？
天地大同 2011-06-24 11:21
你试试把原来的系统波长改成632.8nm，看看Geometric MTF    30 per mm 的mtf值是不是0.54403234
sansummer 2011-06-24 14:30
啊...这倒也是。换了波长的确可能有所变化。另外还有就是如果现在百分比太低，我是否应该考虑把最敏感的公差再紧一些，就会好了？
天地大同 2011-06-28 14:14
恩，多多尝试
sansummer 2011-06-28 15:04
最后一个问题，你的头像怎么换的？哈哈
天地大同 2011-06-28 16:09
是啊  本来没有的  最近刚弄的
sansummer 2011-06-28 18:02
多谢多谢，我也换头像啦

自己看看书不是一样可以解决吗？

楼主分享一下学习ZEMAX公差分析的心得吧。我也刚刚学习这块，很是晕，不知怎么入手。看了一些相关资料，总说蒙特卡洛分析可以模拟生产装配的实际情况，我就是不知道他是如何做到的
zhujiehui 2012-02-27 16:32
学习一下啊
雷伽多 2012-03-07 17:37
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。。。
nanuto 2012-03-09 18:38
好样的
licc 2012-08-04 10:38

请问，公差设置的阿贝偏差应该设置成多少呢？

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？

楼主的头像太慎人！

     公差分析这里 我也不是很清楚 ，学习一下

一起学习下 \mu';[gLd
