[en] In our contribution, we outline the different steps in the design of a fiber-fed spectrographic instrument
for stellar astrophysics. Starting from the derivation of theoretical relationships from the scientific requirements
and telescope characteristics, the entire optical design of the spectrograph is presented. Specific optical
elements, such as a toroidal lens, are introduced to improve the instrument’s efficiency. Then the verification
of predicted optical performances is investigated through optical analyses, such as resolution checking.
