Yeah, that's why I originally intended to use a fiber coupler. But you are right, getting the light of both LEDs into one fiber directly at the start seems to be way better. I kinda blocked my mind with the idea of coupling two fibers. Thanks!
So from my understanding now, I would have to focus...
Hi,
I am looking for a suitable method to couple light from 2 LEDs into a fiber and then join both fibers, so that I only have one fiber at the end so that both wavelengths can be emitted from a single fiber.
The first coupling step from LED into fiber seems to be more easy, I already heard...
