petzval物镜 双远心




petzval物镜怎么实现双远心呢?
我试着改了一下zemax自带镜头库的结构,如附加所示:
不知这是不是petzval物镜?还有 我只设了一个波长,二维图显示的为什么是三种色线呢?
恳请高人指点~~

Check the setting in layout, maybe you set displaying as all fields.

谢谢 确实是设的全视场,改一下就好了 我还是不确定这个结构算不算petzval物镜 ,我看资料上说petzval物镜的F数一一般都小,且两个正透镜间的空气厚度值是焦距的一半,可我这个远远超出了。。。麻烦您指点一下谢谢

Sorry, I cannot reply in Chinese. The Petzval objective consists of two separated positive groups of elements. The system rear principal plane is located between the groups.
you can design a petval config first and combine two of the same config together to get the infinite system.

那要怎么实现像方远心呢?还有 petzval物镜对焦距有范围值么?

I sent you a message, pls check.

这怎么能叫匹兹伐双远心呢????

看一下我发的这个帖子。

上个帖子是本论坛的,图片题小了。

http://www.opticsky.cn/read-htm-tid-64535.html 看一下这个。第三个第四个是匹兹伐的,最后一个是三片镜的。
你的这种事双胶合镜片组成的双远心光路。我这个帖子里也有图片。
