A spectrometer () for gas analysis is provided, the spectrometer comprising a measurement cell () having a gas to be investigated, a light source () for the transmission of light () into the measurement cell () on a light path (), a filter arrangement () having a Fabry-Perot filter (-) in the light path (), in order to set frequency properties of the light () by means of a transmission spectrum of the filter arrangement (), as well as a detector () which measures the absorption of the light () by the gas () in the measurement cell (). In this connection the filter arrangement () has a plurality of Fabry-Perot filters (-) arranged behind one another in the light path () and a control unit () for the filter arrangement () is provided in order to change the transmission spectrum by setting at least one of the Fabry-Perot filters (-).
