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.
