Abstract
An optical measuring device determines a concentration of measurement gas in a sample gas by light absorption. The optical measuring device includes a light source, a deflecting mirror, a primary mirror, a secondary mirror and a radiation detector. A section between the light source and the deflecting mirror is configured to receive the sample gas. The light source is configured to emit light in the direction of the deflecting mirror. The deflecting mirror is configured to act as a collimator for incident light and to deflect the incident light in the direction of the primary mirror. The primary mirror and the secondary mirror are configured to direct the light deflected by the deflecting mirror onto the radiation detector.
