The Advanced Optical Systems Center (CSOA) is an unique infrastructure in Spain for the manufacture of high quality optical elements. This cutting-edge technology is a rising value and, with the necessary requirements in Astrophysics, it is available to very few centers in the world.

HARMONI is one of the three ELT (European Extremely Large Telescope) first light scientific instruments. It is a visible and near-infrared (0.47 to 2.45 µm) integral field spectrograph, providing the ELT's core spectroscopic capability, over a range of resolving powers from R (≡λ/Δλ) ~4000 to R~20000.

ESPRESSO is a fiber-fed, cross-dispersed, high resolution, Echelle spectrograph which can be operated with one or up to 4 Unit Telescopes (UTs) of ESO’s VLT.

OSIRIS is a camera and intermediate spectrograph in operation in the GTC telescope. OSIRIS has various observation modes: direct image, wide slit and multi-slit, which can be combined with charge shuffling and tunable filters. It includes a focal plane mask loader for multi-object spectroscopy.

New multi-object spectrograph planned for the 4.2m William Herschell Telescope (WHT) located in the Observatorio del Roque de los Muchachos, on La Palma island.

High-resolution spectrograph for the 10-m Gran Telescopio Canarias (GTC) based on components from UES, a spectrograph which was in use at the 4.2-m William Herschel Telescope (WHT) between 1992 and 2001.
