A cuvette for a spectrometric analysis instrument has two opposing windows (73, 76) 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 analysed, 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 standardised in order to be able to provide uniform calibrations for said plurality of instruments.

Cette invention concerne une cuvette destinée à un instrument d'analyse spectrométrique, laquelle cuvette comprend deux fenêtres opposées (73, 76) faites d'un matériau qui est transparent à la lumière émise à la longueur d'onde utilisée pendant l'analyse. Ces fenêtres définissent un trajet lumineux limité pour un faisceau de lumière qui va traverser la cavité à l'intérieur de la cuvette. Lorsque l'on utilise des cuvettes comportant des fenêtres qui sont faites d'un matériau, tel que du diamant, possédant un indice de réfraction sensiblement différent de celui du fluide à analyser, les surfaces des fenêtres formant la cavité de la cuvette ne sont pas parallèles. De cette manière, les distances internes qui séparent des zones opposées desdites surfaces des fenêtres vont varier sur toute la surface des fenêtres transparentes. Ainsi, toutes les réflexions internes se produisant dans la cavité vont s'additionner selon une phase quasi aléatoire, ce qui permet d'éliminer toute tendance de résonance. Ce système présente de grands avantages lorsqu'un instrument fait partie d'un groupe d'instruments qui doivent être normalisés afin d'obtenir des étalonnages uniformes de ces derniers.
