What you will do: |EKu2We*

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; ,7W:fwdR
<$%X<sDkq
2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; k1)%.pt%
EI jI!0j
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; H&#{l)

4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… 1B|8ZmFJj

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

let me know how thing's going.
