DEVICE FOR RECORDING OF INFRARED SPECTRUM OF SAMPLE EMISSION Russian patent published in 2009 - IPC G01J3/443 

FIELD: physics, measuring.

SUBSTANCE: device for recording of infrared spectrum of the sample emission contains radiation source, spherical mirror, optically related to plane of the sample and the first flat mirror located on one optical axis with perceiving system, the receiver registering radiation, and the computer handling signals. Also the system of condensers and the additional flat mirror erected in a focal plane of system of condensers and optically related to plane of the sample are entered into the device consistently located on one optical axis with a radiant of radiation. The perceiving system is erected behind the first flat mirror on a course of optical beams from it and contains consistently located a diaphragm with programmed control of a step of its disclosing and an agglomerating mirror, optically related with each other. Thus diameters of a spherical mirror and a diaphragm and distance between them are compounded among themselves and spotted by that radiation from a spherical mirror does not fall outside the limits diameter of a diaphragm. As a radiation radiant the valve by power of 100 watt is used, for example, a xenon one.

EFFECT: increase of informativeness of the registered emission spectrums and device simplification.
