<p>The spectrophotometer comprises a light source (13), a first diffusing element (17), a second diffusing element (24), a test cuvette filled with the fluid to be investigated arranged between the first (17) and second light diffusing element (24) and a photodetector (26) adjacent to the second light diffusing element (24). Light coming from the source (13), is randomly scattered within the first light diffusing element (17) transmitted through the test fluid (21) in the cuvette (20) gathered by the second light diffusing element (24) and converted into an electric signal by photodetector (26). The electric signal is then further processed and monitored by an appropriate electronic circuitry (30, 32, 35). The light diffusing elements (17) and (24) are preferably integrating spheres. </p> |
