ABSTRACT:
The combination of a cuvette for receiving a medium undergoing change in optical characteristics which change modifies the energy level of a ray of energy passing through the medium and wherein the cuvette is provided with integrally formed first and second ray modifying optical means, such as collimating and collecting lens, wherein the first ray modifying optical means receives and modifies the ray in a first manner, such as by collimation, and transmits the ray into the medium and wherein the second ray modifying optical means receives and modifies the ray in a second manner, such as by collection, upon the ray passing through the medium and transmits the ray from the cuvette; and an electrical circuit including photoemissive and photosensitive means, such as a photoemitter and photodetector, wherein the photoemissive means is in intimate optical contact with the first ray modifying optical element of the cuvette and wherein the photosensitive means is in intimate optical contact with the second ray modifying means.
