Abstract: A measuring apparatus for measuring a spectrum of a gaseous sample includes



a tunable laser light source to provide an illuminating light beam,
a sample cell with an inner surface to provide scrambled light that is transmitted through the gaseous sample,
a detector to detect intensity of transmitted scrambled light and
a pressure control system to maintain an absolute pressure of the gaseous sample smaller than 50 kPa inside the sample cell to reduce spectral widths of spectral features of the gaseous sample. The measuring apparatus measures spectral transmittance values of the sample by modulating the spectral position of the illuminating light, and detecting the intensity of the transmitted light at different spectral positions. The divergence of the illuminating light beam in a transverse direction is greater than 30° to cause multiple consecutive reflections of the scrambled light from the inner surface.
