Abstract

An optical gas sensor (), for quantitatively measuring a concentration of one or more gases, includes a radiation source () for emitting light waves (L), a cuvette () for holding a gas (G) to be measured, and a detector () for measuring light intensities. The light source () includes at least one emitter () of light waves (L) and is configured to emit light waves (L) of at least one first wavelength and of a second wavelength different from the first wavelength simultaneously or separately from each other. The emitter () is further configured to emit a spectrum the full half-life width of which is a maximum 50% of the effective wavelength, and to emit light waves (L) having a controlled beam path. The detector () is configured to quantitatively detect an intensity of emitted light waves (L) of the first wavelength and of the second wavelength.
