大侠近来看看,怎么用ZEMAX设计这样一个透镜,谢谢

左边有一个直径2-3毫米的石英玻璃棒(NA1=1.064),
右边有一个62.5/125微米的多模光纤(NA2=0.2),
要在这个玻璃棒和光纤间放置一个耦合透镜,使从玻璃棒一端输出的黑体辐射通过此透镜后最大限度的耦合到光纤,

请问怎么用ZEMAX设计这样一个透镜,谢谢

石英玻璃棒 NA1=1.064 ? ;8VvpO^G/ O:^m#:[cE OR ~-dL #; #"3az8u 石英玻璃棒 NA1=0.064 ?

我想先放掉这个参数NA具体是多少. \|izf\|*e 我很想知道怎么用ZEMAX对这个设想进行设计?? d7O\p(M1 谢谢大侠们先

hi,

What you will do:

1, Please check the system requirement carefully, since fiber 62.5u*NA0.22 is not sufficient for your application, try other fiber and ensure fiber core*NA>3*0.064;

2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture;

3, 3rd order design, to figure out how many spherical lenses OR how many aspherical lenses are needed, and the focal power of each individual lens;

4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting…

Hope above helpful.

Again,

Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39.

let me know how thing's going.
