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.

    JEFFREY R. KUHN: “In our lifetime we are going to wake up some morning to the news that we have discovered life”
    The Sun is not the live coal that Anaxagoras described. We can imagine hell in its interior, and we know that there are darker spots on its surface which, when...
