Hello, I have a question similar to post “dichroic mirror in NSC mode”.
In that question, the supplied example is not in one single configuration, which the emitted light and the excitation light are seperated. I am having trouble simulating the same configuaration but with one dichroic mirror.
I followed the example “How to model fluorescence using bulk scattering”, but the coating on the dichroic mirror does not seem to function on the back surface (Sample side, Green in the figure). Even if I put a reflective surface at the back surface, the incoming ray (black in the figure) from the source side will hit that surface and reflect away. How should I avoid this sitation?
I would like to have the source sending ray transmitting through a 45 degree dichroic mirror, hitting the sample, reflect back to the other surface of the dichroic, and reflect to 90 degree respect to source (upward in the figure). Is that possible? It seems to be an easy task, but I don’t have a solution.
Thank you for your help.
