| In this work we present the characterization and coupling process of the Cananea High-Resolution Spectrograph (CanHiS) of the Observatorio Astrofísico Guillermo Haro (OAGH), at Cananea, Sonora, from the acquisition of the instrument at the University of Arizona (UA), until its commissioning at the OAGH and the observation of the first spectra of stellar objects, aimed at determining the abundances of individual chemical species. We first carried out a complete characterization of the opto-mechanical CanHiS properties and optical performance analysis, culminating with a comprehensive optomechanical simulation of the spectrograph, and we showed the advantages offered by CanHiS. Its principal feature is the adjustable quasi-Littrow mounting, that, combined with the use of medium-band interference filters, makes CanHiS an instrument with very high spectral resolution capabilities and efficiency (R ≈ 85 000 − 185 000, and ≈ 36%, respectively). Since the original opto-mechanical specifications were incomplete and not precise, we carried out a complete and detailed characterization of the whole instrument. Finally, we conducted an analytical study of the expected performance and we compared it with the results of a commisioning observing run, showing an excellent match. | |
