我在Code V中使用zemax to cv的宏进行档案转换之后,又使用plasticprv的宏添加了几个自定义材料,看了下镜头的Lay out发现光线有问题,就set vig设置了下渐晕,但是MTF很低,而且出现了如下的提示:
14:28:47 发出的命令:SET VIG -> 警告: Make surface apertures oversize on surfaces where the caustic
can provide more than one ray at a given height on
the surface (for example, near intermediate or last images).
14:28:47 发出的命令:SET VIG -> 警告: For this rotationally symmetric system axial X-vignetting
has been generated by zoom position 1.
has been generated by zoom position 2.
has been generated by zoom position 3.
14:28:47 发出的命令:SET VIG -> 警告: For this rotationally symmetric system axial Y-vignetting
has been generated by zoom position 1.
has been generated by zoom position 2.
has been generated by zoom position 3.
有没有大佬帮忙看看是哪里出了问题呢?谢谢!
首先,像面前面加一个虚拟面,别让像面直接和前面镜片接轨;
然后,检查一下你的材料是不是都OK的(有时候会遗失);
再然后检查其他变焦位置是否正确;
接着检查非球面或者反射面或者其他特殊面型的导入是否正确;
最后渐晕前中心主光线一下。
一般而言厚度、曲率、非球面系数、渐晕、孔径、视场这些参数不会导错
