| Zusammenfassung: | An optical absorption measuring instrument for determining the percentage of a component in a fluid shall be improved such that changes in the measuring radiation caused by drift or temperature have only a limited effect on the measuring result. Provisions are made for deflecting the measuring beams (
10, 11
) from a radiation source (
4
) to a detector (
5
) by at least two plane mirrors (
71, 72
), which are positioned such that the measuring beams (
10, 11
) emitted by the radiation source (
4
) are deflected to the detector (
5
). The surface of each plane mirror (
71, 72
) is dimensioned to be such that its illuminated surface in the area of the detector (
5
) is larger than the receiving surface (
12
) of the detector (
5
). |
