FIELD: physics.
SUBSTANCE: Fourier spectrometre, having a radiation source, condensers, fibre-optic inputs and collimators, also has a blackbody radiator which is optically connected to an additional condenser and an additional fibre-optic input, as well as with one of the two collimators.
EFFECT: high accuracy, sensitivity and efficiency of measurement.
