hi, xl1L4R)6D )nf=eU4| What you will do: 4*@G&v?n b#?ai3E 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; $gj+v+%N <M5{.`o 2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; BLl%D c,3'wnui 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; Tx|SAa=V _mIa8K; 4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… 9 AQ96 1]D/3! Hope above helpful. ^g}gT-l% XwHu:v'= Mang2004 !0>!tW Fy4< [[/ }1% w /Bn2bD Again, J]kP` !0!P.Q8>& Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39. }"g21-T^ 1)P<cNj let me know how thing's going.
