Abstract
A device () for determining the concentration of a gas component is configured with a radiation source () for emitting () a light radiation or heat radiation in an infrared wavelength range. A detector array () has at least two detector elements (), configured to detect the radiation generated by the radiation source (), in an angular arrangement () and with filter elements (). At least one of the two detector elements () is oriented in an angular arrangement () in relation to a vertical axis (), so that a range of overlap () is obtained due to the angular arrangements (). The range of overlap () causes attenuations in the propagation of light, which attenuations may be due, for example, to gas molecules or moisture (), affect both detector elements () and are thus compensated concerning the concentration determination.
