Abstract: Disclosed herein is a measuring probe, an apparatus, and a method for infrared spectroscopy. In some embodiments the measuring probe may have an elongated form with a first end for coupling and decoupling infrared light into and out of the measuring probe and a second end. In other embodiments, the measuring probe may comprise an attenuated total reflection (ATR) prism arranged at the second end of the measuring probe. The ATR prism may include at least a first surface having at least one measuring portion configured to be brought in optical contact with a measured object. The ATR prism may include at least a second surface having at least one reflective portion. In some embodiments, the ATR prism may include a cutting portion for cutting through the measured object.

Abstract: Disclosed herein is a measuring probe and an arrangement for measuring spectral absorption, preferably in the infrared. Furthermore, the invention relates to a method for spectroscopically measuring absorption. The measuring probe may comprise a cutting apparatus configured to cut a slice or respectively flap off of a sample to be measured; a measuring gap configured to accommodate the sample slice; an optical window element for coupling measuring light into, or respectively out of the measuring gap; and an end reflector designed and arranged to reflect the measuring light propagated through the measuring gap back into the measuring gap. The arrangement for measuring spectral absorption may comprise the measuring probe, a light source and an apparatus for the spectral analysis of the measuring light coupled out of the measuring gap.
