hi, ]b@:?DX8 N~M-|^L What you will do: o=doL{# $e![^I]` 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; a~[]Ye@H _l.kbfp@ 2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; 3)qtz_,H/g 5nG$6Hw 3, 3rd order design, to figure out how many spherical lenses OR how many aspherical lenses are needed, and the focal power of each individual lens; '=m ?l "8`f x 4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… y]E ?\03" 2<5s0GT'/ Hope above helpful. !8>tT .;9I:YB$ Mang2004 WqRg/ Nv_"?er+y nc%ly * E@\bFy_!>b Again, $+a2CZs!
