Abstract: Optical encoding of a cuvette or other object is provided by means of multiple facets molded integrally into flanges or other portions of the object, which facets selectively refract light passing therethrough in accordance with a predetermined code. The detector for the coded light includes a separate detector for each code state of the facets, with the detector having a different output when no facets are between a light source and the detectors. The facets are preferably bevels, which are selectively angled in accordance with the code.
