A first, upper slotted disk (10) and a second, lower slotted disk (20) are arranged as a gas inlet (11) in a gas-measuring device (1). The first, upper slotted disk (10) and the second, lower slotted disk (20) are connected to one another and to a sensor housing (2) via a spacer element (29). The arrangement of the slotted disks (10, 20) in relation to one another is selected to be such that reduced propagation of light of an infrared radiation source (43) through both slotted disks (10, 20) into the measuring environment is achieved.
