What you will do: F+BCz sm7$

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; "8?Fl&=Q
uxKO"
2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; e87 a9ZPm
S{MB$JA
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; p NQ7uy

4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… up8d3

Hope above helpful. aYc<C$:NC"

Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39. z9

let me know how thing's going.
