I have an application where a telescope will be receiving light from a laser source, and I need to couple the output, which is the image cone, into an optical fiber. Does anyone have any suggestions as to the most efficient way to do this?

    $\begingroup$ is the image cone necessary when incoming photons travel in parallel paths and can exit parallel? $\endgroup$

  • $\begingroup$ Welcome Anthony to Engineering and Physics Stack Exchanges. I notice this question is cross-posted on physics. This is discouraged but not forbidden, but when a question is cross-posted it is polite to provide a link on each question to the other so people know and don't duplicate effort. See this and this for an example of how this is done. $\endgroup$ Commented Aug 31, 2023 at 13:28
