hi, q"OJF'>w5

What you will do: b$,~S\\c
R{0nk
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; VKtZyhK"h
g UAx8=h
2, Paraxial ( 1st order ) analysis by manual calculation or in Zemax; to get the magnification, total optical length, lens focal length and aperture; ~ MZEAY9
'G|M_ e
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; 2*5]6B-(
PQJI~u9te}
4, Zemax modeling, optimization, in-stock lens searching, radius test plate fitting… aZBS!X

Hope above helpful. rq]zt2

Please find attached paraxial model in zemax, assuming your obj=2mm, NA0.064, and the fiber is 0.3mm, NA 0.39. Z H1U Af

let me know how thing's going.
