hi, ?z2jk nNt*} k What you will do: $&cz$jyY k:b/Gq` 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; aq3~!T;W 2\^G['9 2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; XDPL;(? 4p.^'2m 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; "-w^D!C ""co6qo#> 4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… `/#f?Hk= z{ptm7 Hope above helpful. 6cJ<9i
