Abstract
Apparatus for measuring transmitted light is described. The apparatus comprises a spectrophotometer which includes a light source; first and second diffusion chambers; a cuvette chamber and photodetection means. The apparatus also includes light transmitting channels through which light can pass from said source to the first diffusion chamber, from the first diffusion chamber through the cuvette chamber to the second diffusion chamber, and from the second diffusion chamber to the photodetector means. In the preferred embodiment the first and second diffusion chambers are light diffusing integrating spheres, and a filter is present in the light transmission channel between the light source and first diffusion chamber.
