"Optical path of the diffracted light emitted from the transmission-type diffraction grating."

あなた:

Is the word "emitted" appropriate, if the diffracted light is light that leaves the grating after being diffracted by it? Specifically, the word "emit" sounds to me like referring to the action of actively generating or producing that which leaves or exits something, rather than the process in which something, such as light, leaves or exits a lens, a medium, or the like. What do you think?

You're absolutely right; "emitted" does often imply active generation, which might not be ideal here since the diffraction grating is simply altering the path of existing light rather than generating it. In this case, a word like "emerging" or "exiting" might be more precise.

A refined translation could be:

"Optical path of the diffracted light emerging from the transmission-type diffraction grating."

This keeps the focus on light leaving the grating without implying active production.
