hi,
E]G#"EV!Y ^kg[n908Nw What you will do:
>uMj}<g#Z? 4
ZD~i e 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;
7A7=~:l\G S3cjw9V 2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture;
q ld2<W lPcp 17U 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;
"Mt4~vy P'Q|0lB 4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting…
tI651Wm9 oK cgP Hope above helpful.

s>}ScJZK Again,
DP E NYr /S}0u}jID? Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39.
CiE 'FB?#C %U let me know how thing's going.
