Astrophysical instrumentation

Projects

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.

    EMIR - Multi-object Infrared Spectrograph

    EMIR is a wide-field camera and intermediate resolution near infrared spectrograph. It is a criogenic multi-object spectrograph installed and in operation in the GTC telescope. A criogenic robotic reconfigurable slit system allows to obtain spectra from up to 50 objects simultaneously.

    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.

    FRIDA - inFRared Imager and Dissector for Adaptive optics

    FRIDA (inFRared Imager and Dissector for Adaptive optics) is an integral field spectrograph in the near infrared, also with image mode, which will be installed in the GTC telescope. It will use the adaptive optics system of GTC (GTCAO) to observe with very high spatial resolution and spectral resolutions of up to 30,000.

  • Fiber link (brazo de fibras ópticas) de NIRPS
    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).
