hi, H|_@9V 8_E(.]U What you will do: _Vl~'+ e }hsNsQ 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; Gy[anDE& c4u/tt.) 2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; v6|j.; Xt:$H6
y 3, 3rd order design, to figure out how many spherical lenses OR how many aspherical lenses are needed, and the focal power of each individual lens; Do7 7V5 +HPcvu?1 4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… D;s%cL` <S=(`D Hope above helpful. sE'c$H c:e3hJ Mang2004 0%Le*C'yk ^r-d.1 -b
iE _|4R^*/4 Again, "P0!cY8r >|c?ZqW Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39. Ka6u*:/ $#-rOi / let me know how thing's going.
