<p>The invention relates to cryostats for infrared detectors. The inventive cryostat consists of: a vacuum chamber (1) comprising an inlet port (7); a first infrared detector (2) which is located in the chamber (1); a second infrared detector (3) which is located in the chamber (1); and a first spectral separator (5) which is located in the chamber (1). Said spectral separator, which comprises a film, is arranged such that each of the infrared detectors (2, 3) in the chamber (1) receives a spectral range of external light which passes through the inlet port (7), said spectral ranges being different to one another. According to the invention, the cryostat can be used, in particular, in an aircraft nacelle.</p> |
