ABSTRACT:
An infrared spectrometer comprises first optical means for focussing a beam of light in a point-shaped area of a sample (19), second optical means for focussing upon a detector (26) the light emitted by the sample, and third optical means permitting the visual observation of the point-shaped area (19). The second optical means of this arrangement are so designed that they pick up the light reflected by the point-shaped area (19). The arrangement of the invention permits measurements to be performed on extremely small areas and even on samples which are not or hardly pervious to light in the infrared range.
