Abstract
A device () for determining the concentration of a gas component is configured with a radiation source () for radiating () light as a light emission in an infrared wavelength range. Two detector arrays () with two detector elements () are configured suitably for detecting the light emission generated by the radiation source () in two detector arrays (). Two filter elements () are associated with the detector elements (). The two detector elements () are oriented in relation to the radiation source, so that a range of overlap () is obtained due to the two detector arrays (). The range of overlap () causes attenuations in the propagation of light, which may be due to gas molecules or moisture (). The attenuations in the propagation of light affect both detector elements () and are compensated concerning the determination of the concentration.
