卡塞格林望远镜到单模光纤的耦合效率各位大侠，我是菜鸟初学者，请问zemax可不可以做卡塞格林望远镜到单模光纤的耦合效率分析，望远镜和光纤之间还要加透镜的吧，哪里可以体现耦合效率呢？谢谢了！

楼主： JZtFt=>q 我曾经做过这种望远系统到光纤的耦合（从概念设计到装调测试）。请把你的问题再讲详细些：如望远系统的视场，焦距，相对口径，工作波段，光纤参数芯径和数值孔径。 L.Lt9W2fi RSi0IfG5 MANG2004

望远镜的实际焦距是3m,已经加了透镜将焦距缩短到了1m左右，利用光纤的口径代替光阑限制望远镜的视场角，望远镜视场角大概为0.1mrad，口径为250mm,工作波段在532nm,光纤数值孔径为0.1，半径2微米。应该从望远镜出来的光要经过透镜之类的才能耦合进单模光纤吧，这个透镜要怎么设计啊，另外zemax也是初学，单模光纤也不太会弄，谢谢指教！

using Calcualtion > Fiber Coupling Efficiency or Geometric Image Analysis or Physical Optics Propagation feopO j6~+ FvNO*'xP there are three option depending on your system set up and the actual modelling you wish to perform

Apologies for late reply as I have been away for a while. The tab "Beam Definition" has a top hat which can be used as collimated beam and the receiving fiber end can be defined under the tab Fiber Data. If you have a single mode you can pick up a Beam Type to closely match your fiber mode and then define the other physical parameter accordingly.

Its a very simple example but does contain some setup you may wish to refer to at the beginning.
