Abstract
The infrared detector includes a sensitive retina capable of detecting a radiation in the wavelength range between 8 and 14 micrometers; and a package containing the sensitive retina and including a window located opposite to the retina, said window comprising a substrate at least partially transparent in the wavelength range between 2 and 14 micrometers; and a set of optical filters formed on the window to attenuate an incident radiation on the retina in a wavelength range between 2 and 8 micrometers, and respectively an optical filter formed on a first surface of the window and attenuating the incident radiation in a first interval of the wavelength range between 2 and 8 micrometers, and a periodic diffraction grating formed on a second surface of the window and attenuating the incident radiation in a second interval of the wavelength range between 2 and 8 micrometers, different from the first interval.
