FIELD: measuring equipment.
SUBSTANCE: device for recording the sample emission in the middle range of the infrared spectrum comprises an external radiation source, a condenser system, the first flat mirror, a spherical mirror. An IR-array with the possibility of longitudinal and transverse displacement relative to the rays emanating from the second flat mirror is used as the recording system. The array is placed behind the focal plane of these rays. The distance from the focal plane to the receiving system is such that the diameter of the IR-emission beam coincides or is close to the size of the entrance window of the recording array.
EFFECT: increased information content of the registered emission spectra and simplified device.
