各位大俠，我是菜鳥初學(xué)者，請問zemax可不可以做卡塞格林望遠(yuǎn)鏡到單模光纖的耦合效率分析，望遠(yuǎn)鏡和光纖之間還要加透鏡的吧，哪里可以體現(xiàn)耦合效率呢？謝謝了！

一起學(xué)習(xí)

我曾經(jīng)做過這種望遠(yuǎn)系統(tǒng)到光纖的耦合（從概念設(shè)計(jì)到裝調(diào)測試）。 請把你的問題再講詳細(xì)些：如望遠(yuǎn)系統(tǒng)的視場，焦距，相對口徑，工作波段，光纖參數(shù)芯徑和數(shù)值孔徑。 nb #)$l

望遠(yuǎn)鏡的實(shí)際焦距是3m,已經(jīng)加了透鏡將焦距縮短到了1m左右，利用光纖的口徑代替光闌限制望遠(yuǎn)鏡的視場角，望遠(yuǎn)鏡視場角大概為0.1mrad，口徑為250mm,工作波段在532nm,光纖數(shù)值孔徑為0.1，半徑2微米。應(yīng)該從望遠(yuǎn)鏡出來的光要經(jīng)過透鏡之類的才能耦合進(jìn)單模光纖吧，這個(gè)透鏡要怎么設(shè)計(jì)啊，另外zemax也是初學(xué)，單模光纖也不太會弄，謝謝指教！

there are three option depending on your system set up and the actual modelling you wish to perform

thanks a lot!

設(shè)計(jì)過300mmRC耦合，多種單光路和多光路的光纖耦合，可以聯(lián)系yaoyaogr@126.com

卡塞格林望遠(yuǎn)鏡的口徑250MM嗎 yyM`J7]J

請教：光源為準(zhǔn)平行光  而接收光纖為10微米0.15的單模光纖在pop如何設(shè)置呢

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.
