Astrophysical instrumentation


The instrumentation to detect and analyze the light in the infrared range of the spectrum is one of the fields of knowledge of the Instrumentation Division. The design and construction of infrared cameras and spectrographs requires high vacuum and cryogenic technologies, involving the specialties of mechanical engineering, optics and electronics, mainly. The integration and operation of mechanisms and devices in a cryogenic environment is especially complex and requires highly specialized knowledge and equipment. The Instrumentation Division has a long history of international participation in this type of instrumentation.

    NIRPS (Near Infra Red Planet Searcher)

    NIRPS is a next-generation, near-infrared spectrograph that uses adaptive optics and is fed via a fiber link. It is a compact cryogenic Echelle spectrograph, capable of operating alone or in combination with the HARPS instrument. It will have a spectral resolution of 100000 or 75000, and will be installed in La Silla observatory (Chile).

  • Infografía 3D de HARMONI

    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.

    MIRADAS - Mid-resolution InfRAreD Astronomical Spectrograph

    MIRADAS is an intermediate resolution infrared spectrograph for the GTC telescope. It will operate in the infrared range of 1 to 2.5 microns with a spectral resolution of 20,000. It is a multi-object spectrograph capable of observing up to 20 objects simultaneously, by means of a robot with 20 arms that can patrol a 5 arcminutes field.

    Infrared high-resolution echelle spectrograph for the Great Telescope CANARIAS (GTC) of the Observatorio del Roque de los Muchachos in the island of La Palma. The main scientific objective of the instrument is to measure the radial velocity (RV) with very high precision (goal of 1 m/s) in the near infrared.
