1. An infrared, IR spectrometer comprising:

  • a first tunable IR laser for providing a first beam at a first wavelength;

    a second tunable IR laser for providing a second beam at a second wavelength;

    a first absorption cell arranged to receive both first and second beams;

    a second absorption cell arranged to receive both first and second beams;

    a first optical absorption detector arranged to detect said first wavelength;

    a second optical absorption detector arranged to detect said second wavelength; and

    an interlacer arranged to alternately block said first and said second absorption cells,wherein said interlacer is an optical chopper comprising at least one reflective blade angled to direct transmitted IR radiation from one of said optical absorption cells on to both of said optical absorption detectors.
