    Abstract: The present invention is concerned with a spectrophotometer useful for determining light transmission of microsamples. It is particularly concerned with a spectrophotometer system using an improved microcuvette and extremely small optical elements for providing and acting upon the light beam that is used in determining the light-transmission characteristics of the sample. It is more particularly concerned with a double-cavity cuvette for receiving in one of the cavities of the cuvette a comparison or reference material and, in the other, the sample to be measured. Even more particularly it is concerned with a doublecavity micro-cuvette particularly adapted for utilizing a shifted-beam light system in which the beam is alternately refracted in different directions to direct it alternately through one cavity and then the other.

    Abstract: The present invention relates to optical instruments, such as photometers including spectrophotometers, and relates more particularly to a light-shifting device of light refracting type for receiving a beam of light used in such instruments and shifting it into one or the other of two parallel paths.
