Imagine this: you have a collimated source, to collect light into the optic fiber (NA= 0.5) you use a plano convex lens (NA = 0.16). The numerical aperture of the lens is small enough so that the light reach the optic fiber with an angle smaller than the acceptance angle of the fiber and is...

Hi all, I'm facing an issue: I'm using a NA = 0.16 lens to focus light into an optic fiber with NA = 0.5 (I'm using that lens because I want it to be compatible even with a NA = 0.22 optic fiber I want to use in the future), but what is the aperture of the output of the optic fiber? I'd say...
