Infrared 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.

    Small Magnetic Loops Connecting the Quiet Surface and the Hot Outer Atmosphere of the Sun
    Sunspots are the most spectacular manifestation of solar magnetism, yet 99% of the solar surface remains "quiet" at any time of the solar cycle. The quiet sun...

    Smooth kinematic and metallicity gradients reveal that the Milky Way's nuclear star cluster and disc might be part of the same structure
    Context. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters. Nevertheless, these clusters are not...
