Abstract
A cuvette for a spectrometric analysis instrument has two opposing windows made of a material, which is transparent to the light of the waveband used for the analysis. The windows define a limited light path of a light beam passing through a cavity inside the cuvette. When using cuvettes having windows of a material, such as diamond, having a refractive index considerably different from the fluid to be analyzed, the window surfaces forming the cuvette cavity should not be parallel, thereby ensuring that the internal distances between opposed areas of the window surfaces will vary across the transparent windows. Thereby any internal reflections within the cavity will add in almost random phase, avoiding any tendency to resonance. This is very advantageous when the instrument is a member of a plurality of instruments, which must be standardized in order to be able to provide uniform calibrations for said plurality of instruments.
