How can we couple the light beam into fiber cable through achromatic lens?

01 March 2023 0 8K Report

The NA of lens is 0.33, focal length is 7.5 mm and the NA of fiber core is 0.29.

Then if we eject the light from dichroic mirror and then passed through the lens, then what will be the setup? Please suggest me. How far the fiber cable will be settled from the lens?
