Spectrometer and method of operating same

摘要

A spectrometer has a first and second light sources (12, 14) which generate light radiation (24) in a first and second wavelength ranges, and a mirror unit (16) for deflecting the light radiation (24, 26) into a measurement path (18), arranged so that the radiation of both wavelength ranges (24, 26) runs through on the same optical path. A detector (20) detects radiation (24, 26) running through the measurement path (18) and an evaluation unit (22) evaluates the radiation (24, 26) incident at the detector (20) and for determining a concentration of a measurement gas component present in the measurement path (18). The mirror unit (16) is configured as a micromirror array (32) and that a single micromirror (34) only deflects a portion of the radiation (24, 26).

1. A spectrometer comprising:
a first light source (12) generating light radiation (24) in a first wavelength range at a first optical path; a second light source (14) generating light radiation (26) in a second wavelength range at a second optical path; a mirror unit (16) for deflecting the light radiation (24, 26) in the first and second wavelength ranges into a measurement path (18), wherein the radiation (24, 26) of both wavelength ranges runs through on the first and the second optical path which are the same; a detector (20) for detecting the radiation (24, 26) running through the measurement path (18); and an evaluation unit (22) for evaluating the radiation (24, 26) incident at the detector (20) and for determining a concentration of a measurement gas component present in the measurement path (18), wherein the mirror unit (16) is configured as a micromirror array (32) and wherein a single micromirror (34) only deflects a portion of the radiation (24, 26).
