The ArmazoNes High Dispersion Echelle Spectrograph, or ANDES, will be a second-generation instrument designed for use at the ELT (Extremely Large Telescope). As a fibre-fed echelle spectrograph, it consists of three spectral arms that cover a wavelength range from 0.4 to 1.8 μm, with the potential to extend its coverage from 0.35 to 2.4 μm. This versatile instrument delivers an impressive spectral resolution of approximately 100,000, allowing for highly sensitive observations of astronomical objects and phenomena, including exoplanets, fundamental scientific inquiries, and various cutting-edge research applications in the field of astronomy. We are working on the opto-mechanical design of the three cameras inside the YJH spectrograph. The mechanical design is based on an improved strategy already used in instruments like OMM/CPAPIR, CFHT/WIRCAM, CFHT/SPIRou, and ESO/NIRPS. The optical design is very effective and simple, as it uses the same four lenses for each band (Y, J and H).
