我現(xiàn)在再用zemax做均勻化照明，出現(xiàn)了很多問題，急需指點(diǎn)。 |s
WH!:]49  
這是一個(gè)non-sequential系統(tǒng)，我用fly's eye lens array做均勻化， \N1G5W  
1.怎么計(jì)算lens的焦距，這個(gè)問題涉及到最后均勻照明區(qū)域的大小 7<&
CN0&  
2.怎么限制lens的edge，比如fly's eye lens array 的cell 的edge值 和 隨后fourier lens的edge？ JCNZtWF  
3. 是否可以用NSDD直接來限制均勻照明區(qū)域的大�。� lUXxpv1m

我的基本想法是： M|e Qds  
l_JPkM(mJw  
1.首先NSDD來限制照明區(qū)域大小尺寸                            ol^J-  
2.設(shè)定fly's eye lens array 的radius， thickness為變量，來求均勻照明。 nU$;W

我的問題是 希望直接用透鏡焦距比來控制照明區(qū)域的尺寸，但是不知道怎么求焦距？ (hTe53d<S?

希望有經(jīng)驗(yàn)的高手多多指教！

My personal opinion is u online search for ready-made microlens arrays then continue with ur design. This will definitely reduce the cost as starting a new precision molding no doubt will shoot up the cost. You may design in sequential mode because it is faster and easier.Non-sequential mod getting slower when the N number increase. 2<Lnfc<^k  
Go Suss microoptics website search for an excel file which is very very helpful this design.Under homogenizer section. D2

Do take note that if your source is high coherency, the grating effect and speckles may donimate. <^+~?KDZM  
Sorry for not typing in Chinese cos my this computer not able to do so.But I do understand Chinese.I have a few this type of designs but cannot share out due to confidential issue. enjoy trying dude!

在nonsequential中，我一旦設(shè)置 lens array radius， conic coonstant， lens thickness E,,)?^
