SYNOPSYS 光学设计软件课程十四：更具挑战性的优化
is%ef
$%&OaAg
从平面平行的表面开始设计了一个七片透镜的镜头，这个镜头很接近我们的设计要求。 该课程旨在展示PSD III优化算法的速度。 @3b @]l5
在本课程中，我们将从相同的初始结构开始 - 但在这种情况下，我们希望四个视场都能实现高MTF，并将目录玻璃类型替换为前一课程的玻璃模型。 为了做到这一点，我们将使用自动实际玻璃插入程序ARGLASS &>Y.$eW_

如果这看起来像你所追求的那样，将ADT监视器添加到AANT文件中并进一步优化以修复薄透镜。分析镜头以找出问题，然后告诉AANT。 IG I$,C
我们建议您自己运行此练习。尝试更改一些视场权重或孔径权重，然后再次运行。结果对这些变化非常敏感，当你设计自己的镜片时，你需要了解哪些控制有效，哪些控制无效。 WC g&*
这个例子从平面平行板开始，产生了一个相当不错的镜头。如果你运行它会发生什么。 @E?o~jO(e
