1. An infrared optical gas analyzer, comprising:

  • a cuvette containing the gas mixture to be measured;

    a first multispectral detector, containing a ray-mixing system in the form of a pyramid system;

    a first infrared optical radiation source positioned such that the radiation emitted in a first wavelength range reaches the first multispectral detector through the interior space of the cuvette;

    a second multispectral detector, containing said ray-mixing system in the form of said pyramid system;

    a second radiation source provided such that the radiation emitted in a second wavelength range reaches the second multispectral detector through the interior space of the cuvette, said first wavelength range and said second wavelength range being selected such that they will be different from one another;

    a pneumatic diaphragm, arranged between the two paths of rays integrated in the cuvette.
