Abstract: A robust, compact spectrometer apparatus for determining respective concentrations or partial pressures of multiple gases in a gas sample with single as well as multiple and even overlapping absorption or emission spectra that span a wide spectral range. Embodiments may include at least a scanning mirror or diffraction grating (46) and a beam splitter (44) for dviding and dispersing a collimated input beam (40) into plural bands may include, for example, infrared bands of 3 to 5 micrometers and 7 to 10 micrometers.
