Title: Cuvette configured for photoanalysis use

Abstract: A cuvette for containing a fluid to be analyzed by a single or multiple passage therethrough of a light beam whose rays are substantially parallel to each other. The cuvette is configured such that the substantially parallel light rays incident onto the cuvette remain substantially parallel after one or more passages of the light rays through the cuvette or the light rays have a minimum beam diameter at a selected distance from the cuvette. This is accomplished while the cuvette has a fluid holding configuration that minimizes contamination of subsequent sample placed therein.
